11. The world’s tallest battle monument is found in Houston. It’s called the San Jacinto Monument and it was dedicated in 1939 and stands 570-feet high, 15-feet above the Washington monument. Ride the elevator to the observation deck to get a view of the site of one of the biggest battles in our nation’s history. They also have a museum on-site; it’s located 20-minutes from downtown Houston. It’s actually the second tallest monument in the country, right after the 630-foot Gateway Arch in St. Louis.
