Architecture Landmarks of Chicago

Built during the time when Chicago reigned as the undisputed rail center of the United States, Union Station handled as many as 300 trains and 100,000 passengers daily. Upon its completion Union Station was hailed as an outstanding achievement in railroad facility planning and is one of the most historically significant passenger railroad stations in the United States. Today the monumental Neoclassical station is the last-remaining great railroad terminal still in use in Chicago. The station’s ornate Beaux-Arts main waiting room, the “Great Hall,” is one of the United States’ great interior public spaces with its vaulted skylight and connecting lobbies, staircases, and balconies.
