Located at 89 meters in height, the Pedres castle was built between 1296 and 1322 during the Pisan-Aragonese domination period during the ascent of the Visconti family. It is characterized by two squares, one upper and one lower, surrounded by polygonal walls, reachable through stairs built with large granite boulders. Its position allowed to control the territory up to the Gulf of Olbia.
In 1339 the castle was entrusted to the hospital friars of Saint John of Jerusalem. From the second half of the fourteenth century it was occupied by the Aragonese and then by the Giudicato of Arborea. The castle met a definitive abandonment at the beginning of the fifteenth century, coinciding with the decline and depopulation of Civita.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
