Visiting the Gateway Arch: Enter the monument through the Gateway Arch Visitor Center, which faces Fourth Street and the Old Courthouse. The Gateway Arch legs are exits only. Please allow at least 30 minutes to go through security.
Head to the mezzanine inside the Gateway Arch Visitor Center for these special daytime activities:
At 8 p.m., meet at the west entrance of the Gateway Arch for “Ghosts of the Arch Grounds,” a ranger-led twilight talk. Long before the Gateway Arch was built, the area served as the core of St. Louis, evolving from a French-style fur trading post to a warehouse district, to the present-day national park site. Learn about the events, personalities and tragedies involved in the development of a great city.
Weather permitting, this talk will be followed by free telescope viewing on the West Entrance Plaza from 8:30 to 10 p.m., led by volunteers from the St. Louis Astronomical Society. The nearly full moon and other objects will be seen. The ranger talk will be cancelled in the event of heavy rain, while the telescope viewing will need at least partly clear skies. Call 314-655-1708 the afternoon of May 18 for an update on the weather status.
