![]() Gateway Arch National Park consists of the Gateway Arch itself, the free history museum under it, the 90 acres of beautiful landscape that surround it, and the Old Courthouse, which was already 100 years old when the arch was built. It has been a unit of the National Park Service since 1935, when 40 city blocks were designated Jefferson National Expansion Memorial by Roosevelt's Executive Order 7253. In 2018, the park was renamed Gateway Arch National Park by an Act of Congress. Security NoteAll park visitors must pass through a security checkpoint. No weapons — including pepper spray — are allowed. If you have pre-purchased your tram ticket, please arrive before your tram time to ensure you have enough time to make it through security before boarding the tram.
