Torre del Oro

Historia

The Torre del Oro is a dodecagonal military watchtower in Seville, southern Spain. It was erected by the Almohad Caliphate in order to control access to Seville via the Guadalquivir river.Constructed in the first third of the 13th century, the tower served as a prison during the Middle Ages. Its name comes from the golden shine it projected on the river, due to its building materials .The tower is divided into three levels, with the third and uppermost being circular in shape and added in 1769. The Torre de la Plata, an octagonal tower, is located nearby, and is believed to have been constructed during the same era.Military functionIt is one of two anchor points for a large chain that would have been able to block the river. The other anchor-point has since been demolished or disappeared, possibly from collapsing during the 1755 Lisbon earthquake. The chain was used in the city's defense against the Castilian fleet under Ramón de Bonifaz in 1248 Reconquista. Bonifaz broke the river defenses and isolated Seville from Triana. The besieged Muslim city soon surrendered to the Christian forces.Historical roleThe Tower of Gold was built 1220-1221, by order of the Almohad governor of Seville, Abu l-Ulà, with a twelve-sided base. It barred the way to the Arenal district with a section of wall joining it to the Tower of Silver, a part of the city walls that defended the Alcazar.
