Fodor's Expert Review Torre del Oro

Built by the Moors in 1220 to complete the city's ramparts, this 12-sided tower on the banks of the Guadalquivir served to close off the harbor when a chain was stretched across the river from its base to a tower on the opposite bank. In 1248, Admiral Ramón de Bonifaz broke through the barrier, and Fernando III captured Seville. The tower houses a small naval museum.
