Gateway Arch National Park, formerly the Jefferson National Expansion Memorial, is a United States National Park in St. Louis, Missouri. The primary attraction is the Gateway Arch which commemorates the westward expansion of the United States. St. Louis used to be known as the “Gateway to the West”, which is why it was selected as the location for this monument.
In addition to the arch, the park also includes the Old Courthouse building nearby.
The park was given national park status in 2018 at the end of a long renovation of the visitor center and the arch. It is by far the smallest site with a national park designation in the US.
Despite the controversy surrounding giving the site national park status, it is still an incredible structure and one of the most impressive monuments in the world.
