Maritime museum of Seville's seagoing past.
Built in the early 13th century by the Moors as part of the city's defenses against the Christians, the 12-sided Torre del Oro, or Gold Tower, on the bank of the river by the Puente San Telmo, is one of Seville's most famous landmarks. It's name is said to come from originally having been tiled with gold (which may or may not be true), or because it was used as a store for precious metals arriving from the Americas. It has also been used as a gunpowder store and a prison. In the 19th century there was a plan to demolish it, but popular opposition saved the day. The riverside area around the tower was remodelled for the 1992 Expo, and it now stands alongside a pleasant riverside promenade. The museum inside the tower holds a collection of maritime exhibits from Seville’s seagoing past.
