Pedres Castle

It is a medieval fortress, built of local stone in the mid-13th century, during the Visconti period of the Judicato of Gallura, and subsequently used by the Pisans to withstand the attack of the Aragonese.Until 1296, Nino Visconti was judge of Gallura (he was also the last), who used it for military purposes. His daughter Giovanna, who was unable to succeed him, took over his real estate assets, including this castle.The fortress's main role was to defend Civita and the borders with the Judicate of Torres.Originally the castle was equipped with four towers and was characterized by two squares, an upper and a lower one, surrounded by polygonal walls, accessible by stairs made of large granite blocks. In the upper square two ruined rooms are still visible, one of them with a groin vault, a cistern to collect rainwater and the keep, originally divided into four floors and allowing control of the area up to the Gulf of Olbia. Access to the tower was about 6 meters high and was via extendable wooden ladders.In 1339 the castle was entrusted to the Hospitallers of Saint John of Jerusalem. From the second half of the 14th century it was occupied by the Aragonese and then by the Judicate of Arborea. At the beginning of the 15th century there was a final abandonment, which was accompanied by the decline and depopulation of Civita (later Terranova Pausania).Most of the damage the fortress has suffered is due to neglect and neglect over the past few decades, but some is also due to the bombing of the last war.In the years following the conflict, it was also used as a functional structure for the administration of the nearby Olbia-Venafiorita airport.Source: it.wikipedia.org/wiki/Castello_di_Pedres
