About Washington Monument
The Washington Monument is a 555-foot (169 m) tall obelisk on the National Mall in Washington, D.C., built to commemorate George Washington, a Founding Father of the United States and the nation's first president. Standing east of the Reflecting Pool and the Lincoln Memorial, the monument is made of bluestone gneiss for the foundation and of granite for the construction. The outside facing consists of three different kinds of white marble, as the building process was repeatedly interrupted. The monument stands 554 feet 7+11⁄32 inches (169.046 m) tall, according to U.S. National Geodetic Survey measurements in 2013 and 2014.
