St. Louis Arch
The St. Louis Arch on the bank of the Mississippi River marks the city as the "Gateway to the West." Thomas Jefferson's vision of freedom and democracy spreading from "sea to shining sea" inspired architect Eero Saarinen's contemporary design for a 630-foot stainless steel memorial. Construction began in 1963 and was completed on October 28, 1965. The Arch's foundation is set 60 feet into the ground and is built to withstand earthquakes and high winds. A 40-passenger train takes sightseers from the lobby to the observation platform, where on a clear day the view stretches for 30 miles.
