Soaring 555 feet above the National Mall in Washington DC, the Washington Monument honors our first President, George Washington. Construction on the monument began on July 4 1848, and the capstone was laid on December 6 1884. At the time, it was the world's tallest structure and held that honor until the Eiffel Tower was completed in 1889.

Visitors can take an elevator to the top of the monument for breath-taking views of 30-40 miles on clear days, and spectacular views of the Capitol on any day.

The Lincoln Memorial is the icon of memorials. The memorial itself is memorialized on the penny, making this one of the most recognizable in America.
