Candidate passages:
Navy Pier is a long pier on the Chicago shoreline of Lake Michigan.
It is located in the Streeterville neighborhood of the Near North Side community area.
The pier was built in 1916 at a cost of $4.5 million.
It was a part of the Plan of Chicago developed by architect and city planner Daniel Burnham and his associates.
As Municipal Pier #2 (Municipal Pier #1 was never built), Navy Pier was planned and built to serve as a mixed-purpose piece of public infrastructure.
Its primary purpose was as a cargo facility for lake freighters, and warehouses were built up and down the Pier.
However, the Pier was also designed to provide docking space for passenger excursion steamers, and in the pre–air conditioning era parts of the Pier, especially its outermost tip, were designed to serve as cool places for public gathering and entertainment.
The Pier even had its own tram.
Today, Navy Pier is Chicago's number one tourist attraction.
Construction began in 1914 under the leadership of Charles Sumner Frost and took two years, at a total cost of $4.5 million.
When it opened to the public in 1916, it was the largest pier in the world.
The Pier was built both to handle shipping and as an entertainment site.
The original Burnham Plan proposed five piers, but only one was commissioned.
In 1917-18, during World War I (WWI), the Pier housed many Navy and some Army personnel, the Red Cross, and Home Defense units.
It even had a jail for draft dodgers. 
From 1965–1989, Navy Pier was considered underutilized.
In the bicentennial year of 1976, opened by a concert by Fort Sheridan's 81st Army Band, Navy Pier began its fourth life as an area for public exhibits, when the East Buildings (furthest into Lake Michigan) were opened as exhibition halls.
Special events including music and arts festivals (ChicagoFest was one) began to draw crowds to the Pier despite its aging infrastructure.
The halls were used to represent Atlantic City, New Jersey, in the 1986 movie The Color of Money for the 9-Ball Championship.
From 1979 to 1987, a submarine, the USS "Silversides", was docked at Navy Pier.
In 1989, the Metropolitan Pier and Exposition Authority took control over the Pier.
Major renovation and construction followed in the 1990s at a cost of US$200 million.
As rebuilt in the 1990s, the Pier's layout included fast-food kiosks, shops, a ballroom, a concert stage, and convention exhibition halls.
Centerpiece attractions include a Ferris wheel, an IMAX theater, the Chicago Shakespeare Theater, Amazing Chicago's Funhouse Maze, the Chicago Children's Museum, the Smith Museum of Stained Glass Windows, and at the entrance to Navy Pier is a statue of Oak Park comedian Bob Newhart, sponsored by the TV Land network.
The Pier now features a large front lawn showcasing numerous larger-than-life public art sculptures and an interactive animated fountain created by WET (of Fountains of Bellagio fame).
The Pier continues to be used as an embarkation point for tour and excursion boats and is a popular place to watch lakefront events, including the annual Air and Water airshow and the parade of lighted and decorated boats during Chicago's Venetian Night festival.
The Pier and its grounds encompass more than of parks, gardens, shops, restaurants and other shore entertainment.
Navy Pier contains 170,000 total square feet of exhibition space, of reception space and of meeting room space. 
The land that Pier Village now sits on was originally that of the Long Branch Pier and the Kid's World amusement park.
On June 8, 1987, at around 3 PM, a fire broke out underneath the boardwalk in an electrical and gas box at the end of the pier.
The fire quickly spread throughout the pier despite efforts by the Long Branch Fire Department to save it.
After the fire only the water attractions across the street from the pier remained.
In the following weeks business had slowed down so the remaining portion of Kid's World closed down permanently at the end of the summer.
The owner, Pat Cicalese, planned on rebuilding the pier.
However, his insurance did not cover the cost to rebuild what was destroyed and the town would not fund the project so the plans were abandoned.
What was left of Kid's World remained abandoned for 17 years after the fire.
Remains of the pier were demolished in the late 1990s.
The rest of Kid's World across the street met the wrecking ball in 2002.
Applied Development Company, a Hoboken, NJ-based developer led by brothers David Barry and Michael Barry, was designated the developer of the site by the City of Long Branch and soon began construction of Pier Village, starting with the rebuilding of the boardwalk. 
Built in 1844 and originally named Terrace Pier, the prefix "Royal" was added in honour of Princess Alexandra of Denmark, who arrived at the pier on her way to marry Edward, Prince of Wales in 1865.
River pilots have been based at this pier since the late 19th century.
Today, Royal Terrace Pier is in constant 24-hour use, as part of the Port of London Authority main operations centre.
However, public access is available occasionally during the year.
The pier's construction was funded by the Gravesend Freehold Investment Company, at a cost of £9000.
It is 'T' shaped, with a pontoon at the pier head.
Like Town Pier, Royal Terrace Pier is also a Grade II listed structure.
