The Washington Monument

The Washington Monument is a large, white-colored obelisk at the west end of the National Mall in Washington, D.C. It is a United States Presidential Memorial constructed for George Washington. The monument is made of marble, granite, and sandstone. It was designed by Robert Mills, a prominent American architect of the 1840s. Upon completion, it became the world's tallest structure at 169 m, a title it inherited from the Cologne Cathedral and held until 1889, when the Eiffel Tower was finished in Paris, France. The Washington Monument reflection can be seen in the aptly named Reflecting Pool, a rectangular pool extending to the west, towards the Lincoln Memorial.
