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.
The pier was built even before Huntington Beach was an official town.
At the time, the land was owned by a business called Huntington Beach Company, which decided to build a pier in 1903.
It was made completely out of wood and extended into the ocean.
In 1912, it was damaged for the first time by a severe storm that caused a large portion of it to plunge into the Pacific.
Fortunately, the city council at the time was already considering rebuilding the pier.
A $70,000 bond was approved to construct a new pier made of concrete that would be long.
In 1914, the Huntington Beach Pier set a record as the longest and highest concrete pleasure pier in the United States.
In 1930, the city extended the pier by and added a cafe at the end.
However, this last section was not built well and was separated from the original pier by an earthquake in 1933.
Although the city paved over the gap, a rare California hurricane destroyed the cafe and extended section in 1939.
Reconstruction of the pier and End Cafe (what the cafe came to be called) was completed the year later.
After the Japanese bombing of Pearl Harbor in 1941, Huntington Beach, along with many other coastal cities, became involved in the World War II effort.
The U.S. navy took over the pier for military use by installing a submarine lookout post at the end along with a heavy caliber machine gun.
When the war was over, all military equipment was removed and the pier was returned to the citizens.
The pier did not face any trouble for the next four decades, until 1983 when another storm destroyed the end of the pier and End Cafe again, and once again in 1988 after another reconstruction.
That year, a company called Fluor/Daniel Consultants of Irvine conducted a study on the structural stability of the pier and as a result, the pier was declared unsafe and was closed in July of that year.
In an effort to raise funds to rebuild the pier, a group of citizens formed an organization called P.I.E.R.
(Persons Interested in Expediting Reconstruction).
The organization raised over $100,000 by selling t-shirts and other merchandise with the P.I.E.R.
logo.
Another $92,000 was donated by the people of Anjo, Japan, one of Huntington Beach's sister cities.
With this money, construction of a new pier began in October 1990.
The pier was completed and opened on July 18, 1992 at in length.
A ribbon-cutting ceremony was performed to dedicate the pier.
By the end of the grand opening day, over 500,000 people had come to visit the new pier.
Due to the pier's rough history, the city has established careful management and observation to keep the pier lasting long into the future.
The pier was added to the U.S. National Register of Historic Places (NRHP) on August 24, 1989, deeming the structure worthy of preservation by the federal government.
This allows the city of Huntington Beach to qualify for tax incentives derived from the total value of expenses incurred preserving the pier. 
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. 
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. 
Probably the oldest pier on the Cromarty Firth built by Thomas Telford in 1821, The 9th report to the Commission on Highland Roads and Bridges, 1821, noted " a Landing Pier of massive dimensions has been erected for the express purpose of facilitating the importation of lime, coals and other articles of consumption in the very fertile district of Easter Ross, and for the exportation of corn and timber."
the cost is noted as amounting to "about Two Thousand Four Hundred Pounds; of which Mr Kenneth Macleay contributes a Moiety."
The pier still stands today but as of June 2012 the pier is in a very poor state and much of it is beginning to collapse.
