10The Washington Monument, Washington D.C.
Situated on the National Mall, this monument is a tall, obelisk vaguely akin to ancient Egyptian pyramids. Built to honor the famous commander-in-chief of the well-known Continental Army and the very first president of the United States, George Washington. It is constructed of bluestone gneiss, granite, and marble.
It was designed by architect Robert Mills in the early 1840s. Construction began in 1848 and was completed in 1888. (Work was interrupted by the US Civil War.) It is 554 high and was the world’s tallest monument until the Eiffel Tower was completed in 1889.
