Torre del Oro

Tower in Seville

One of Seville's signature landmarks, this 13th-century riverside watchtower was the last great building constructed by the Muslims in the city. Part of a larger defensive complex, it supposedly had gilded tiles, hence its name, ‘Tower of Gold', although some dispute this, claiming the name is a reference to the fact that conquistadors returning from Mexico and Peru used the tower to store booty they'd siphoned off colonial coffers. Today, it hosts a small maritime museum and a rooftop viewing platform.
