# Monmouth County, New Jersey

Monmouth County (/ˈmɒnməθ/) is a county located in the central portion of the U.S. state of New Jersey. It is bordered to its west by Mercer and Middlesex Counties, to its south by Ocean County, to its east by the Atlantic Ocean, and to its north by the Raritan Bay (sharing a border with the boroughs of Staten Island, Brooklyn, and Queens in New York City, across it). Monmouth County's geographic area comprises 30% water. The county is part of the Jersey Shore region of the state. It has also been categorized under the Central Jersey region, though it was not among the four counties explicitly listed as included in Central Jersey as part of legislation signed into law in 2023.
As of the 2020 United States census, the county was the state's fifth-most-populous county with a population of 643,615, its highest decennial count ever and an increase of 13,235 (+2.1%) from the 2010 census count of 630,380, which in turn reflected an increase of 15,079 from 615,301 at the 2000 census. As of 2010, the county fell to the fifth-most populous county in the state, having been surpassed by Hudson County. Monmouth's county seat is Freehold Borough, though many county offices are also located in neighboring Freehold Township. The most populous place was Middletown Township, with 67,106 residents at the time of the 2020 Census, while Howell Township covered 61.21 square miles (158.5 km$^2$), the largest total area of any municipality.
While there are differing historical theories, the most plausible of theories in the origin of the county's name are attributed to many settlers originating from Rhode Island where the Rhode Island Monmouth Society hailed from, or it being named after the historic county of Monmouthshire in Wales, Great Britain. The county, like much of the state, was significantly involved during the American Revolutionary War. The Battle of Monmouth was fought in June 1778 in what has been preserved as Monmouth Battlefield State Park, currently located in Freehold Township and Manalapan Township.
The county's economy is rich and diverse, due to its high population density and proximity to New York City. Located in the middle of the Northeast megalopolis, its inland county seat of Freehold Borough, the Tri-City region of coastal cities of Red Bank, Long Branch, and Asbury Park, along with the county constituting a vast swath of the New Jersey coastline, has contributed in its draw of tourists throughout the state (and much of the Northeastern United States at large), particularly during the summer months. Many communities within the county serve as commuter towns to and from New York City and other points north. Highways such as the Garden State Parkway, U.S. 9, Route's 34, 35, and 36, along with NJ Transit's North Jersey Coast Line and Seastreak, connects county residents to economic centers in North Jersey and New York City. In 2015, the county had a per capita personal income of $69,410, making it the fifth highest in New Jersey and ranked 74th of 3,113 counties in the United States. Many inland areas of the county are still quite agricultural, with many orchards, wineries, equestrian farms, and distilleries, such as Cream Ridge Winery, Delicious Orchards, Four JG's Orchards & Vineyards, and Laird & Company. The Bell Labs Complex is a major scientific research facility in Holmdel Township, where important breakthroughs, such as evidence for the Big Bang, were discovered. The county is also home to Monmouth University, a private university in West Long Branch.

## History
### Etymology

The naming of Monmouth County has different historical theories. It is thought that the county received its name from the Rhode Island Monmouth Society. This is likely, due to many of the county's earliest settlers originating from Rhode Island. Another plausible theory, is from a suggestion from Colonel Lewis Morris that the county should be named after Monmouthshire in Wales, Great Britain. Other suggestions include that it was named for James Scott, 1st Duke of Monmouth (1649–1685), who had many allies among the East Jersey leadership.

### Indigenous history

Around the year 1000, the area of Monmouth County began to be inhabited by the Lenape Native Americans prior to the arrival of European settlers. They came from the Mississippi River area. They lived along the vicinity of the Jersey Shore, the Raritan Bay, the Raritan River and other areas in the northeastern United States. The Lenape were a hunter-gatherer society. They were largely sedentary, changing campsites seasonally. They were prolific hunters of small game and birds. They were also skilled fisherman, and were known to harvest vast amounts of clams from the bays and inlets on the Jersey Shore. They also practiced some agriculture to augment their food supply. During this time, an important crossroad of two major Lenape trails was located in the area of Freehold Township in western Monmouth County.

### Colonial era

In 1609, the English navigator, Henry Hudson, and his crew aboard the Dutch vessel Half Moon spotted land in what is now Monmouth County, most likely off Sandy Hook; however, some historical accounts credit this landing to present-day Keansburg. Among the first European settlers and majority landowners in the area were Richard and Penelope Stout. Penelope "miraculously" survived her wounds from a native attack in Sandy Hook and lived to the age of 110. A group of Quaker families from Long Island settled the Monmouth Tract, an early land grant from Richard Nicolls issued in 1665. They were followed by a group of Scottish settlers who inhabited Freehold Township in about 1682–1885, followed several years later by Dutch settlers. As they arrived in this area, they were greeted by Lenape people, who lived in scattered small family bands and developed a largely amicable relationship with the new arrivals. Enslaved Africans were present in the area from at least 1680, and by 1726 made up 9% of the total population of the county.
Monmouth County was established on March 7, 1683, while part of the province of East Jersey. On October 31, 1693, the county was partitioned into the townships of Freehold, Middletown and Shrewsbury.
In 1764, the Sandy Hook Lighthouse was built.
At the June 28, 1778, Battle of Monmouth, near Freehold Township, General George Washington's soldiers battled the British under Sir Henry Clinton, in the longest land battle of the American Revolutionary War. At Monmouth the tactics and training from Friedrich Wilhelm von Steuben developed at Valley Forge during the winter encampment were first implemented on a large scale. Other battles and massacres during the war in Monmouth County include sites such as the Burrowes Mansion in Matawan, and the Allen House in Shrewsbury.
At independence, Monmouth's population included 1,640 slaves, as well as an undetermined number of free African Americans. The number of enslaved persons fell steeply after 1820, though a small number remained until at least 1850. Monmouth's free African American population climbed from 353 in 1790 to 2,658 in 1860. There was a small African-American middle class consisting of freedmen present in Monmouth County by the 1840s and 1850s.
In 1790 Monmouth County's population was 16,918, of whom roughly 6,600 were of English descent and the remainder were Welsh, Dutch and Swedish, as well as small amounts of African Americans and Northern Irish Protestants. By 2010 Monmouth County's population was 628,112 of whom 40,489 were of English descent. Between 1890 and 1907 nearly 18 million European immigrants came to America. At the same time the region underwent massive and not unrelated economic changes, this process led to places like Monmouth County, New Jersey becoming significantly more diverse and somewhat less rural.

### 19th century

In 1822, James P. Allaire bought land that would be used to establish the Howell Works Iron Foundry in what is now Wall Township. The village was an early example of a company town, having its workers live on site with numerous types of stores and facilities for them. The furnace had ceased to operate by 1848 as iron and coal production moved to Pennsylvania. Today, the land is a living history museum and U.S. historic district known as Allaire Village.
On May 18, 1826, the Navesink Twin Lights were commissioned by Congress, and were first used in 1828. The twin lighthouses were one of only seven in the country. However, this structure deteriorated rapidly, and was in need of replacement. On May 1, 1862, the current structure was first lit at a much grander scale. Upon completion, it was the most powerful lighthouse in the United States. In 1883, it became the first lighthouse in the country to use a mineral-oil lamp. Today, the lighthouse is open to the public as a U.S. historic landmark and place.
In 1848, one of the original Life Saving Stations was built in Sandy Hook for the United States Coast Guard. Between 1857 and 1867, construction began on the Fort at Sandy Hook. The fort remained nameless until 1895 when it was named Fort Hancock after Winfield Scott Hancock. On August 7, 1874, the Sandy Hook Proving Ground was established as a weapons testing area, considered a separate facility from the fort. In 1890, construction began on the artillery batteries of the fort. The Battery Porter was an early prototype of the gun lift carriage.
During the 19th century, Keyport's Marine Park was a major shipbuilding hub, having built 55 steamships between 1807 and 1868, which was more than Hoboken, Jersey City, or Camden during this period.
In 1850, Ocean County was carved out of Monmouth County.
On July 30, 1870, Monmouth Park Racetrack opened, a thoroughbred racing track in Eatontown. The facility closed and reopened several times, with the current facility having been in use since 1946.
On September 19, 1881, U.S. President James A. Garfield died in the Elberon section of Long Branch, a few months after being shot in a failed assassination attempt. Garfield was one of several presidents who would vacation in Long Branch around the Gilded Age, with other presidents who frequented the town including Chester A. Arthur, Ulysses S. Grant, Benjamin Harrison, Rutherford B. Hayes, William McKinley, and Woodrow Wilson.
On July 5, 1886, the Seabright Lawn Tennis and Cricket Club in Rumson opened as the first lawn tennis club in the United States.
In 1888, Palace Amusements opened in Asbury Park alongside the boardwalk, and contained numerous amusement rides and games, such as a carousel. After years of a declining economy within the city, the palace closed in 1988, 100 years after it opened. In 2004, the building was deemed unsafe, and was ordered to be demolished, although various elements were saved such as the iconic Tillie mural and the carousel.
In 1899, Guglielmo Marconi's first demonstration of the wireless telegraph in the United States took place at the Navesink Twin Lights.

### 20th century

In 1910, the Wright Brothers hosted an aviation show in Interlaken, where numerous records were broken, such as high altitudes, longest time airborne, the first night flight, and the first air mail delivery.
Fort Hancock in Sandy Hook played a minor role in World War 1 and World War 2. The fort was intended as one of the defensive forts of New York City, and as neither war came to the area, the fort was largely unaffected. However, during World War 1, several of the artillery guns were removed for use elsewhere. In 1919, the Sandy Hook Proving Ground was essentially abandoned in favor of a large site at the Aberdeen Proving Ground in Maryland. During World War 2, the fort served as a mobilization center. In 1946, the guns at the fort were considered obsolete, leading to their scrapping and subsequent decommissioning of the fort. The fort was reactivated twice, first as an antiaircraft defense and later as a Nike missile base, but was closed for good in 1974. Today, the fort is a National Historic Place and Landmark.
In 1916, two of the three Jersey Shore shark attacks occurred in Monmouth County, with one occurring on July 6 in Spring Lake while the other occurred on July 12 in Matawan. One person was killed in the Spring Lake attack, while in Matawan two people were killed and one was injured.
In 1917, construction of Fort Monmouth began under the name of Camp Little Silver as training grounds. The first permanent structure, a barracks, was erected in 1928. In 1928, the first radio-equipped meteorological balloon reached the atmosphere, a precursor to modern day weather sounding. Numerous buildings were constructed during the 1930s-1940s at the facility, with the fort significantly expanding in size. Fort Monmouth was also where Soviet spies Julius Rosenberg, Joel Barr, and Alfred Sarant operated. Numerous scientific breakthroughs occurred at Fort Monmouth, including Project Diana in 1946; SCORE, the world's first communications satellite in 1958; TIROS-1, the world's first full-scale weather satellite in 1960, and other projects including photography.
On November 11, 1926, the Count Basie Theater opened as the Carlton Theater in Red Bank. In 1970, the theater had closed alongside most of the other historic theaters in the town. In 1973, an anonymous donation allowed for the preservation of the theater. In 1984, it was renamed after Count Basie, a native of Red Bank. Many well-known acts had performed at the theater, such as Tony Bennett, Olivia Newton-John, Bruce Springsteen, and Jon Bon Jovi.
In 1928, the Asbury Park Convention Hall was constructed alongside the boardwalk. On January 1, 1930, the Paramount Theater in Asbury Park showed its first film, Wings. The buildings are connected by a grand arcade alongside the boardwalk.
On September 8, 1934, the SS Morro Castle caught fire and burned during a storm on its route from New York City to Havana, Cuba. The ship drifted ashore to Asbury Park by the Convention Hall, where it remained until 1935 when it was towed away to be scrapped. The disaster was one of the deadliest maritime disasters in United States history, having killed 137 people.
On December 13, 1943, Naval Weapons Station Earle was commissioned, which is designed to safely store and transport military ordinance. The 11,000 acre main facility consumes land in Colts Neck Township, Howell Township, Wall Township, and Tinton Falls, while the three-pronged pier in the Leonardo section of Middletown Township is connected to the main facility via Normandy Road, a military-only railroad and road that connects the facilities.
The Bell Labs complex in Holmdel Township was a major center for scientific research throughout the 20th century. On May 4, 1933, radio astronomy, one of the most significant achievements in the field of astronomy, was invented by Karl Guthe Jansky. On June 25, 1946, the silicon solar cell was patented by Russell S. Ohl, who operated out of Bell Labs. In 1959, AT&T began construction on the current building, completing it in 1962, where the building acted as a research and development facility. The facility was expanded twice in 1966 and 1982. On October 17, 1978, cosmic microwave background radiation was discovered at the site by Arno Penzias and Robert Wilson.
On June 12, 1968, the Garden State Arts Center opened in Holmdel Township alongside the Garden State Parkway, having its own exit of 116. The amphitheater often hosted classical and popular music, as well as various other programs, and has a capacity of roughly 10,000 people. In 1995, on the opposite side of the parkway, the New Jersey Vietnam Veterans' Memorial was opened. In 1996, the facility expanded heavily, adding thousands in capacity, and shifting toward general music with broader appeal to compete with other amphitheaters. In 1996, the facility was renamed to PNC Bank Arts Center. The theater is one of the most successful amphitheaters in the country.
In 1970, Asbury Park experienced a major race riot between July 4 and July 10, one of the largest in New Jersey. The riot was largely due to high unemployment, poor housing conditions, and lack of recreational activities within the African American community. Over 180 people were injured during the week long riot. The largely African American West Side of the city experienced the most damage, with an estimated $5,600,000 in damages.
On February 8, 1974, The Stone Pony opened in Asbury Park across the street from the boardwalk. The live music venue is small but well-known, with its most notable talents Bruce Springsteen and the E Street Band as well as Southside Johnny and the Asbury Jukes having launched their career out of the venue.

### 21st century

In 2005, Fort Monmouth was recommended for closure, and in 2011 the facility shut down for good. Redevelopment of the land had been in talks since 2006, and in 2021 Netflix had announced it was going to create a film studio at the facility. In 2022, a proposal to develop housing units where the fort's housing stands was approved.
In 2006, Bell Labs was sold, and preservation efforts were made by residents and former employees. In 2013, a developer began site redevelopment, with the research building becoming a New Urbanism inspired mixed-use facility, while the surrounding land became residential housing.
In 2016, Monmouth Mall in Eatontown announced that it would be redeveloped into a pedestrian-friendly mixed-used development, including demolition of some of the abandoned parts of the mall, with the addition of housing, plazas and walkways, amongst many other changes. The mall, which opened in 1960, had faced lots of vacancies and financial troubles over the years that led to the decision. The plans were finalized in 2023.
On June 14, 2018, Monmouth Park Racetrack became the first place in New Jersey to offer sports betting.

## Geography and climate

According to the U.S. Census Bureau, as of the 2020 Census, the county had a total area of 661.40 square miles (1,713.0 km$^2$), of which 468.18 square miles (1,212.6 km$^2$) was land (70.8%) and 193.22 square miles (500.4 km$^2$) was water (29.2%).
Much of Monmouth County remains flat and low-lying, even at its western inland extreme. However, there are some low hills in and around Holmdel Township, and one of them, Crawford Hill, the former site of a radar facility, is the county's highest point, variously listed at 380 to 391 feet (116 to 119 m) above sea level. The top portion of the hill is owned by Alcatel-Lucent and houses a research laboratory of Bell Laboratories. The northeastern portion of the county, in the Locust section of Middletown Township and the boroughs of Highlands and Atlantic Highlands, are also very hilly. The lowest point is sea level.
Along with adjacent Middlesex and Ocean counties, Monmouth County is a mecca for boating and fishing. Its waterways include several tributaries that flow from the more agrarian regions of western Monmouth County into the Raritan River, and various rivers and inlets that flow from the more densely populated region of the Raritan Bayshore of northern Monmouth County into the Raritan Bay and the Lower New York Bay, before finally draining out into the Atlantic Ocean. The Manasquan Inlet is located in the county, which connects the Atlantic Ocean with the estuary of the Manasquan River, a bay-like body of saltwater that serves as the starting point of the Intracoastal Waterway, which attracts as many as 1,600 boats each weekend during the peak season.

### Climate and weather

Much of Monmouth County has a humid subtropical climate (Cfa), while some inland areas have a hot-summer humid continental climate (Dfa). In recent years, average temperatures in the county seat of Freehold Borough have ranged from a low of 22 °F (−6 °C) in January to a high of 86 °F (30 °C) in July, although a record low of −13 °F (−25 °C) was recorded in January 1984 and a record high of 106 °F (41 °C) was recorded in July 2011. Average monthly precipitation ranged from 2.98 inches (76 mm) in February to 5.08 inches (129 mm) in July.
Average monthly temperatures in Asbury Park range from 32.5 °F in January to 75.0 °F in July, while in Allentown, NJ they range from 32.1 °F in January to 75.5 °F in July.
On October 29, 2012, Hurricane Sandy caused catastrophic damage to coastal areas of Monmouth County. As Sandy's surge arrived in Monmouth County, flood levels of 13.31 feet (4.06 m) above normal were measured at Sandy Hook shortly before the destruction of the tidal station, breaking all previous local records. The surge caused waves as high as 32.5 feet (9.9 m), measured where the Sandy Hook Bay meets the New York Bay.

## Government
### County government

Monmouth County is governed by a five-member Board of County Commissioners, who are elected at-large for three-year terms of office on a staggered basis, with either one or two seats up for election each year. Each January, the commissioners select one of their members to serve as the director of the board for the year to preside over the meetings and activities of the board. Monmouth County's Commissioners have both administrative and policy-making powers. The commissioners oversee the five mandatory functions of the county government delegated to it by the state. Each commissioner is assigned responsibility for one of the five functional areas: Administration and Special Services; Public Works and Engineering; Human Services, Health and Transportation; Finance and Administration of Justice, overseeing more than 70 county departments in total. In 2016, freeholders were paid $27,000 and the freeholder director was paid an annual salary of $27,900. County Administrator Teri O'Connor, an appointed position, serves as the county's chief executive officer, and is responsible for carrying out the policies and directives established by the Board of County Commissioners and managing the daily operations of the county's more than 3,000 employees.
As of 2025, Monmouth County's Commissioners are (with terms for Chair and Vice-Chair ending every December 31):
| Commissioner | Party, Residence, Term |
| Director Thomas A. Arnone | R, Neptune City, 2025 |
| Deputy Director Ross F. Licitra | R, Marlboro Township, 2026 |
| Erik Anderson | R, Shrewsbury, 2026 |
| Nick DiRocco | R, Wall Township, 2025 |
| Susan M. Kiley | R, Hazlet Township, 2027 |
The Republican Party had held all five Commissioner seats until 2006, but after the 2006 and 2008 elections, Democrats controlled the Board by a 3–2 margin. The Board swung back in favor of the Republicans after the 2009 election when Republican John Curley beat Democrat Sean Byrnes. Both were running to succeed former Commissioner Director Barbara McMorrow, a Democrat, who had chosen not to seek re-election. In 2010, former mayor of Neptune City, NJ, Thomas Arnone (R), and incumbent Commissioner Robert Clifton (R) won seats giving Republicans control of the Board of County Commissioners by a 4–1 margin. The board has been all Republican since 2011.
Pursuant to Article VII Section II of the New Jersey State Constitution, each county in New Jersey is required to have three elected administrative officials known as "constitutional officers." These officers are the County Clerk and County Surrogate (both elected for five-year terms of office) and the County Sheriff (elected for a three-year term). Monmouth county's constitutional officers are:
| Office | Party, Residence, Term |
| Clerk Christine Giordano Hanlon | R, Ocean Township, 2025 |
| Sheriff Shaun Golden | R, Howell Township, 2025 |
| Surrogate Rosemarie D. Peters | R, Middletown Township, 2026 |
Raymond Santiago of Freehold Township is the Monmouth County Prosecutor, having been formally nominated to the position by Governor of New Jersey Phil Murphy in September 2022. Monmouth County constitutes Vicinage 9 of the New Jersey Superior Court and is seated at the Monmouth County Courthouse in Freehold Borough, with additional facilities in Freehold and Ocean Township; the Assignment Judge for Vicinage 9 is Lisa P. Thornton.

### Federal representatives

The 3rd, 4th, and 6th Congressional Districts cover the county. For the 119th United States Congress, New Jersey's 3rd congressional district is currently represented Herb Conaway (D, Delran Township). For the 119th United States Congress, New Jersey's 4th congressional district is represented by Chris Smith (R, Manchester Township). For the 119th United States Congress, New Jersey's 6th congressional district is represented by Frank Pallone (D, Long Branch).

### Fire departments

Monmouth County is covered by 53 different fire departments, which contain 135 individual fire companies and over 7,000 volunteer firefighters, who are all represented by the Monmouth County Firemen's Association.
The Monmouth County Fire Marshal's Office is responsible for training all of the firefighters through the Monmouth County Fire Academy, as well as investigating any fires which may be deemed suspicious and/or involving a fatality. The Monmouth County fire marshal, currently Fred Migliaccio, and his staff – including assistant fire marshals and academy staff – are appointed by the County Board of Commissioners.
Except for the fully professional Asbury Park Fire Department and the US Navy Fire Department at NWS Earle, the remainder of the municipalities in the county have volunteer or combination fire departments. The largest volunteer department is in Middletown Township with 11 stations and 350 active members, special services, air and fire police units, in addition to operating its own training facility.
In terms of hazardous material (HazMat) emergencies, very few towns have special units to respond to these types of emergencies. Fort Monmouth responded to most HazMat cases prior to the closing of the base. Naval Weapons Station Earle is also available for HazMat incidents. Hazardous Materials incidents are currently managed by Monmouth County Hazmat as the lead agency with a joint cooperative team composed of Neptune Township OEM, Southard (Howell) Fire Company and Middletown Fire Department Special Services.
The oldest fire department in the county in continuous operation is the Hope Fire Company in Allentown, organized in 1856. The newest fire department, Holmdel Fire Co. No. 2 was established in 2006. Monmouth County utilizes a mutual aid system, in which surrounding municipalities are available to send their resources to incidents where extra help or expertise is needed.

## Politics

Monmouth County has generally leaned Republican by small margins in federal, state, and local races, though registered Republicans only outnumber registered Democrats by 2.5%.

## Economy

The Bureau of Economic Analysis calculated that the county's gross domestic product was $34.2 billion in 2021, which was ranked ninth in the state and was a 6.1% increase from the prior year.

### Housing expense

In 2015, the county had a per capita personal income of $69,410, the fifth-highest in New Jersey and ranked 74th of 3,113 counties in the United States. Monmouth County ranked 38th among the highest-income counties in the United States as of 2011, placing it among the top 1.2% of counties by wealth. As of 2009, it was ranked 56th in the United States by personal per-capita income.

### Gentrification

Hurricane Sandy in 2012 devastated much of the northern part of the Jersey Shore, particularly in Monmouth County. This necessitated the demolition and rebuilding of entire neighborhoods. Some were rebuilt to a higher economic level; this process of climate gentrification is rapidly escalating property values and transforming many communities along the Shore. Many houses have become vacation homes for the New York financial community, akin to shoreline communities on Long Island like the Gold Coast and The Hamptons.

### Telecommunications and high technology

The Bell Labs Holmdel Complex has been the site of many innovations in telecommunications and is experiencing a renaissance as a business incubator for high-tech startup companies. Today Verizon Wireless, AT&T Communications, Vonage, Avaya, and Bell Labs are located in the region.

### Commerce

The county has been a commercial hub for the state and the larger northeastern United States for years. This is due to the county's location on the Jersey Shore, which attracts residents from North and South Jersey, along with the nearby states of New York, Pennsylvania, Connecticut, Delaware, and Maryland during the summer months. The region also boasts year-round attractions, such as hayrides, wine tasting, and apple picking during the autumn months. The county also features five major shopping malls:
* Freehold Raceway Mall

The company received "Theatre of the Year" awards from the New Jersey Theatre Alliance in 2006, and from The Star-Ledger in both 2006 and 2008. At the July 2009 meeting of the New Jersey State Council on the Arts, Two River Theater was designated as a Major Impact Organization.
* Monmouth County Historical Association – Established in 1898 by a group of county residents headed by professional educator Caroline Gallup Reed, it was soon incorporated in order “to discover, procure, preserve and perpetuate whatever relates to the history of Monmouth County.” The headquarters are located in Freehold Borough in a brick Georgian-style building designed by architect J. Hallam Conover.
* Monmouth County Jewish Heritage Museum - focuses on Jewish life in the county, which dates back to 1720.
* Monmouth Battlefield State Park — Located in Freehold Township and Manalapan Township, the park preserves a rural eighteenth-century landscape of orchards, fields, woods and wetlands, encompassing miles of trails for hiking and horseback riding, space for picnic areas, and four restored Revolutionary War farmhouses that were associated with the American Revolutionary War's Battle of Monmouth, including the Craig House, the Cobb House, the Sutfin House, and the Rhea-Applegate House. The park includes a visitor center with replicas of eighteenth-century canons and other exhibits.
* Gateway National Recreation Area at Sandy Hook - The barrier peninsula segment of the much larger Gateway National Recreation Area (which has other sections in Staten Island, Brooklyn, and Queens in New York) forms the other side of the "gateway" to New York Harbor. It includes two main park sites:
** Fort Hancock served as part of the harbor's coastal defense system from 1895 until 1974 and contains 100 historic buildings and fortifications.
** Sandy Hook contains seven beaches, including Gunnison Beach, a nude beach by custom, as well as salt marshes and a maritime holly forest. Ferries from Manhattan are available in season. Fishing and using hand-launched vessels are popular here.
* Monmouth County Courthouse – In front of the courthouse, is a park at the center of town which hosts a 90-foot (27 m) tall monument to the Battle of Monmouth at its center.
* St. Peter's Episcopal Church — a historic Episcopal church building that was constructed in 1771, featuring Georgian and Gothic Revival elements.
* Ocean Grove Camp Meeting Association District - An association founded in 1869 by a group of Methodist clergymen, led by William B. Osborn and Ellwood H. Stokes. Its mission is to "provide opportunities for spiritual birth, growth, and renewal in a Christian seaside setting." It was to operate as a summer camp meeting site on the New Jersey seashore. By the early 20th century, the popular Christian meeting ground became known as the "Queen of Religious Resorts." The community's land is still owned by the camp meeting association and leased to individual homeowners and businesses. Ocean Grove remains the longest-active camp meeting site in the United States.
* Church of the Presidents - Originally consecrated in 1879 as St. James Protestant Episcopal Chapel, a branch of St. James Episcopal Church, this former Episcopal chapel was where seven United States presidents during the Victorian era worshipped. It was visited by presidents Ulysses S. Grant, Rutherford B. Hayes, James A. Garfield, Chester A. Arthur, Benjamin Harrison, William McKinley, and Woodrow Wilson. All except Grant were in office when they paid their visits to the church.
* Seabrook–Wilson House – Nicknamed the "Spy House" by local residents, the house was built in 1663 in the town of Port Monmouth, a part of Middletown Township, making it the oldest structure in Monmouth County and one of the oldest in the state. The house's architecture was emblematic of the early English influence in the county. For most of its history, the farm on Sandy Hook Bay was home to generations of two prominent Port Monmouth families, the Seabrooks and the Wilsons. Ship owners and captains, a Revolutionary War militia officer, local business owners and investors, and a clergyman were part of these notable families, many of whom served in local government positions.
* Allaire State Park - Historic park, known for its restored 19th century ironworks, Allaire Village, which is a living history museum on the park premises. It was a prosperous industrial town producing pig iron and cast iron from the surrounding bog iron deposits. The buildings which remain and have been restored today include a general store, blacksmith shop, carpenter's shop, manager's house, foreman's house and a church. One of the workers' row house buildings has been recreated and now houses a visitor center, museum, and reenactments of nineteenth-century life in this bustling mill town. The historic village is run by a non-profit organization independent of the park and charges a nominal fee to enter the buildings. It is named after James P. Allaire, founder of the Howell Works at the same site. The park also hosts the Pine Creek Railroad, a tourist railroad.
* Holmdel Park - Located in Holmdel Township, this massive park is part of the Monmouth County Park System. The initial park land was established in 1962, with an additional 227 acres (92 ha) section added in 2001. The park's recreational offerings include fishing (with permit), individual and group picnic areas, tennis courts, playgrounds and 10 miles of hiking trails. Ice skating and sledding are permitted when conditions are deemed safe. The park contains four distinct visitor areas, each with its own parking; three are accessed via the main park entrance while the fourth is located at the activity center further north on Longstreet Road. The park also features:
** Holmdel Arboretum - Also known as the David C. Shaw Arboretum, which contains nearly 3,000 trees and shrubs, representing hundreds of species, cultivars, and varieties, including the Jane Kluis Memorial Dwarf Conifer Garden, a collection of true cedars (Cedrus) in honor of David Rossheim, and a variety of other plantings such as weeping Atlas cedar, cherry trees, Amur cork tree, among many others. A map at the entrance identifies the major plant collections.
** Longstreet Farm - A living history farm museum displaying a recreation of life in the 1890s. Workers dress in period costume, and perform the activities of a resident of the time period, such as planting and harvesting of crops, and taking caring of livestock. The Holmes-Hendrickson House, built in 1754, is a museum operated by the Monmouth County Historical Association near the farm.

### Sports

Monmouth Park Racetrack in Oceanport and Freehold Raceway in Freehold offer fans of thoroughbred horse racing a chance to bet on races. Freehold Raceway announced in September 2024 that they will close, with the final racing date being December 28.
In 1943, the New York Yankees held their spring training in Asbury Park instead of Florida. This was because rail transport had to be conserved during the war, and Major League Baseball's Spring Training was limited to an area east of the Mississippi River and north of the Ohio River.
