At the height of its traffic, during World War II, as many as 200,000 people passed through in a single day. In 1988, a headhouse wing was added and the original station renovated for use as a shopping mall. Today, Union Station is one of the busiest rail facilities and shopping destinations in the country, and is visited by over 40 million people a year.
Union Station is a major train station, transportation hub, and leisure destination in Washington, D.C. Opened in 1907, it is Amtrak’s headquarters and the railroad’s second-busiest station, with annual ridership of over 5 million. The station also serves MARC and VRE commuter rail services, the Washington Metro, and buses.
The Washington Monument is an obelisk on the National Mall in Washington, D.C., built to commemorate George Washington, once commander-in-chief of the Continental Army and the first American president. Standing almost due east of the Reflecting Pool and the Lincoln Memorial, the monument, made of marble, granite, and bluestone gneiss, is both the world’s tallest stone structure and the world’s tallest obelisk, standing 554 feet 7 11⁄32 inches (169.046 m) tall. It is the tallest monumental column in the world if all are measured above their pedestrian entrances, but two are taller when measured above ground, although the latter are neither all stone nor true obelisk
