Union Station

Opened in 1939 on the site of the original Chinatown, it was the last of the great American rail stations to be built, at a cost at the time of $11 million. By 1971, just seven passenger trains a day were running here; however, it's a bit busier today, and its Mission-style exterior, marble floors, high ceilings and decorative tiles make it a handsome place. However, don't confuse it with the Spanish colonial post office that stands next to it.
