This enormous marble obelisk soars to 555 feet and was built as a tribute to first president George Washington. Construction of the monument – which was originally intended to comprise a large pantheon as well as an obelisk – began in 1848, but funds soon dwindled. Work halted and wouldn’t begin again until after the Civil War. It recommenced in the 1870s, under the eye of president Ulysses S. Grant, and the landmark was finally dedicated in 1885. It’s seen here, partially completed, in the 1860s.
