Constructed in the first third of the 13th century, the tower served as a prisonduring the Middle Ages. Its name comes from the golden shine it projected on the river, due to its building materials (a mixture of mortar, lime and pressed hay).
It 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 collapsing during the 1755 Lisbon earthquake. The chain was used in the city's defense against the Castilian fleet under Ramón de Bonifaz in the 1248 Reconquista. Bonifaz broke the river defenses and isolated Seville from Triana.
———布鲁日也有一个类似的圆柱型的什么东西，功能和这个类似，就是像河的门框一样，来往船只必须在此留下买路钱——交税。所以我以为这个也是。但这里是只有军事作用。我还以为有灯塔作用，一定是和里斯本的混了
下次去，我进去看看。现在是个博物馆，好像。
