The remains of the Archbishop’s Towers have their origin in the castle that was built on this same site in the 12th century. Shortly afterwards, King Ferdinand II donated the town and this fortress to the Archbishop of Santiago, who used it as a residence when he visited the city. It suffered serious damage during the confrontation between Alonso II de Fonseca, archbishop of Santiago, and Pedro Álvarez de Sotomayor, better known as Pedro Madruga, during the civil war that between the years 1474 and 1477 faced the supporters of Isabel la Católica and those of Juana la Beltraneja. At the beginning of the 18th century Pontevedra suffered an English attack during which this place was burned and left very deteriorated, with only its great keep being saved, which was used as a prison. At the end of the 19th century it was decided to demolish it. In 2007, during renovation works on this avenue, remains of this fortress appeared. In 2010, the Interpretation Centre was inaugurated.
