The majestic medieval castle of Sciacca was built in 1382 at the wishes of Guglielmo Peralta, count of Caltabellotta, who became one of the four vicars of the kingdom of Sicily after the death of king Fredrik the III. The castle was passed down to the counts of Luna when, after the death of Nicolò Peralta (son of Guglielmo) one of his three daughters, Margherita, married count Artale of Luna, a Catalan and uncle of king Martino.
The castle rises from its dominating position, in the high up, east part of the city, and is located within the perimeters of the ancient walls, that still exist in part today.It is tied to the “Caso di Sciacca”, the century-long bloody battle between the Catalan house of Luna and the Norman house of Perollo, in conflict over a secret love, that of Giovanni Perollo for Margherita, wife of Don Artale Luna, but also for political and economic interests.
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.
