How did Gateway Arch become a National Park?
The Gateway Arch is a monument to the mid-nineteenth-century westward migration of the United States.
The park is dedicated to Thomas Jefferson’s role in opening the West, to the pioneers who helped shape its history, and to Dred Scott, who sued for his freedom at the Old Courthouse.
The US government had been planning to build a monument in St Louis since the 1930s, but it wasn’t until 1965 that Congress finally approved the construction of the Gateway Arch.
In 1935, President Franklin D. Roosevelt decided that the area along the St. Louis riverfront should be turned into a monument.
The City of St. Louis transferred the Old Courthouse to the National Park Service while construction was taking place so that it could become part of the Memorial.
In 1948, a design competition was held to determine the shape of the Memorial, and construction on architect Eero Saarinen’s stainless steel arch design began in 1963.
The Gateway Arch was finished in 1965 and has become a national symbol of both architectural design and American identity.
The original name of the monument was the Jefferson National Expansion Memorial. In 2018 a bill was signed to officially name it Gateway Arch (since that’s what the public called it) and to make it an official National Park.
