Opened in 1894, Union Station was designed by St. Louis architect Theodore C. Link in the Richardsonian Romanesque style. There are also touches of the French Renaissance. You can also detect a hint of King Ludwig II's Neuschwanstein castle in the tower. The train sheds were designed by George H. Pegram. Union Station quickly became one of the world's busiest railroad stations, handling over 100,000 passengers daily in its heyday. The station closed in 1978, but was reborn in 1984 as a hotel and "urban marketplace."
