Awe-inspiring views of the Washington Monument

Rising 555 feet into the sky, the Washington Monument is one of the most iconic landmarks in the nation's capital. Commemorating the country's first president, the massive obelisk was partially erected in 1848 and finished in 1884, at which time it was the world's tallest structure.
