The first reliable evidence of feudalism in Bivona dates back to 11 October 1299, when Robert of Anjou, the King of Naples, granted the castles of Bivona and Calatamauro to Giacomo de Catania. The castle mentioned in this decree was probably a watchtower which had been built as part of the walls of Bivona around the time of the War of the Sicilian Vespers.
Eventually, the castle began to be built in the first half of the 14th century. In 1359, Guido and Francesco Ventimiglia almost destroyed it, but it was rebuilt within the same year by Corrado Doria. The land and castle of Bivona was passed to Nicholas Peralta in 1397. In 1406, it belonged to Francesco Castellar.
The castle was looted and partially destroyed in 1529, during the Secondo caso di Sciacca, a conflict between the de Luna and Perollo noble families.
Today, the castle is in ruins. Some parts of it are embedded in structures of a later period.
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.
