The Jefferson National Expansion Memorial is located in St. Louis, Missouri near the starting point of the Lewis and Clark Expedition. It was designated as a National Memorial by Executive Order 7523, on December 21, 1935, and is maintained by the National Park Service (NPS).
The park was established to commemorate several historical events:
The memorial site consists of a park along the Mississippi River on the site of the original city of St. Louis; the Old Courthouse, a former state and federal courthouse which saw the origins of the Dred Scott case; the Museum of Westward Expansion; and most notably, the Gateway Arch, an inverted steel catenary arch that has become the definitive icon of the city.
Today, the park is host to four million visitors each year, three quarters of whom enter the Arch or the Old Courthouse.
The Gateway Arch is known as the "Gateway to the West". It was designed by Finnish-American architect Eero Saarinen and structural engineer Hannskarl Bandel in 1947 and built between 1963 and 1968. It is the only building in the world based on the catenary arch, making it the iconic image of the city. It stands tall and wide at its base. The legs are wide at the base, narrowing to at the arch. There is a unique tram system to carry passengers to the observation room at the top of the arch.
The courthouse is the only portion of the memorial west of I-70. To the west of the Courthouse is a Greenway between Market and Chestnut Streets which is only interrupted by the Civil Courts Building which features a pyramid model of the Mausoleum of Maussollos (which was one of the Seven Wonders of the Ancient World) on its roof. When Civil Courts building was built in the 1920s the Chouteau family sued to regain the property belonging the Old Courthouse because it had been deeded in perpetuity to be a courthouse.
In the early 1930s the United States began looking for a suitable memorial for Thomas Jefferson (the Washington Monument and the newly built Lincoln Memorial were the only large Presidential memorials at the time).
Shortly after Thanksgiving in 1933 Smith who had been on the commission to build the George Rogers Clark National Historical Park in Indiana, was returning via train when he noticed the poor condition or the original platted location of St. Louis along the Mississippi. He thought that the memorial to Jefferson should be on the actual location that was symbolic of one of Jefferson's greatest triumphs -- the Louisiana Purchase.
The originally platted area of St. Louis included:
Almost all of the historic buildings associated with this period had been replaced by newer buildings. His idea was to raze all of the buildings in the original St. Louis platted area and replace it with a park with "a central feature, a shaft, a building, an arch, or something which would symbolize American culture and civilization."
Smith pitched the idea to Bernard Dickmann who quickly assembled a meeting of St. Louis civic leaders on December 15, 1933 at the Jefferson Hotel and they endorsed the plan and Smith became chairman of what would become the Jefferson National Expansion Memorial Association (a position he would hold until 1949 with a one-year exception).
The Commission then defined the area, got cost estimates of $30 million to buy the land, clear the buildings and erect a park and monument. With promises from the federal government (via the United States Territorial Expansion Memorial Commission) to join if the City of St. Louis could raise money.
The area to be included in the park was the Eads Bridge/Washington Avenue on the north and Poplar Street on the south, the Mississippi River on the east Third Street (now I-70) on the west plus the Old Courthouse just west of Third Street (the Courthouse was actually added in 1940).
The only building in this area not included was the Old Cathedral, which is on the site of St. Louis first church and was opposite the home of St. Louis founder Auguste Chouteau. The founders of the city were buried in its graveyard (but were moved in 1849 to Bellefontaine Cemetery during a cholera outbreak).
Taking away 40 blocks in the center of St. Louis was bitterly fought by some sources -- particularly the St. Louis Post-Dispatch.
On September 10, 1935, the voters of St. Louis approved a $7.5 million bond issue to buy the property.
The buildings were bought for $7 million by the federal government via Eminent domain and was subject to considerable litigation but were ultimately bought at 131.99 percent of assessed valuation.
Roosevelt inspected the memorial area on October 14, 1936 during the dedication of the St. Louis Soldiers Memorial . Included in the party was then Senator Harry S. Truman.
The architectural competition for a monument was delayed by World War II. Interest in the monument was fed after the war as it was to be the first big monument in the post-World War II era.
The estimated cost of the competition was $225,000 and Smith personally donated $40,000. Civic leaders held the nation-wide competition in 1947 to select a design for the main portion of the Memorial space.
Architect Eero Saarinen won this competition with plans for a 590-foot (180-metre) catenary arch to be placed on the banks of the Mississippi River. However, these plans were modified over the next 15 years, placing the arch on higher ground and adding 40 feet (12 m) in height and width.
The central architectural feature at the base of the arch is the Old Courthouse, which was once the tallest building in Missouri and has a dome similar to the United States Capitol and was placed on the building during the American Civil War at the same time as that on the U.S. Capitol.
Saarinen developed the shape with the help of architectural engineer Hannskarl Bandel. It is not a pure inverted catenary. Saarinen preferred a shape that was slightly elongated and thinner towards the top, a shape that produces a subtle soaring effect, and transfers more of the structure's weight downward rather than outward at the base.
When Saarinen won the competition, the official notification was sent to "E. Saarinen", thinking it to be the architect's father Eliel Saarinen, who had also submitted an entry. The family celebrated with a bottle of champagne, and two hours later an embarrassed official called to say the winner was, in fact, the younger Saarinen. The elder Saarinen then broke out a second bottle of champagne to celebrate his son's success.
Among the five finalists was local St. Louis architect Harris Armstrong.
On June 23, 1959, work begins on covering railroad tracks that cut across the memorial grounds.
On September 1, 1961 Saarinen died.
On February 12, 1963 the first stainless steel triangle that forms the first section of the arch was set in place on the south leg.
On October 28, 1965 it was completed, costing approximately US$15 million to build. Along with all other historical areas of the National Park Service, the memorial was listed on the National Register of Historic Places on October 15, 1966. Vice President Hubert Humphrey and Secretary of the Interior Stewart Udall dedicated the Arch on May 25, 1968.
In 1999, the Arch tram queue areas were completely renovated at a cost of approximately $2.2 million.
In 1999 the Ulysses S. Grant National Historic Site in St. Louis County, Missouri was brought under the Superintendent of the Memorial jurisdiction.
In 2007 St. Louis Mayor Francis Slay and former Missouri Senator John Danforth asked the National Park Service to create a more "active" use of the grounds of the memorial and model it on Millennium Park in Chicago including the possibility of an amphitheater, cafes and restaurants, fountains, bicycle rentals, sculptures and an aquarium. The National Park Service is currently cool to the plan noting that the only other overt development pressure on National Park property has been at the Jackson Hole Airport in Grand Teton National Park
The Memorial is separated from the rest of Downtown St. Louis by a sunken section of I-70. The city is considering a $90 million proposal to cover the interstate. The NPS, as part of their Centennial Initiative celebrating its 100th anniversary in 2016, is considering a plan to complete Saarinen's original master plan. The intention is to build the Gateway Arch Connector to link the Old Courthouse with the grounds of the Arch.
