The Castle of Pietrarossa ('Red Stone Castle'), built using, as its name suggests, largely red stones, dominates the city and the whole Salso River valley from the edge of the ravine upon which it stands.
The originsa castle remain unknown. It is presumed to have been built in the 9th century, but there are some historians who claim that it was built by the Sicani, a people that was present in Sicily in the 8th century before the arrival of the Greeks. The castle is towering over the whole valley of the river Salso.
Throughout history some historical events took place, in 1378 an important meeting of the Sicilian barons was held during which 4 were appointed vicars to govern Sicily. Around 1570, a strong earthquake destroyed most of the castle, today there are only two towers left.
The view that you can admire from this castle is spectacular although today the castle is in a state of disrepair. So be very careful when visiting.
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.
