The castle of Asklipio (Asklepieion) was built in 1479 by Grand Master D'Aubusson at the site of an ancient lighthouse. In the Byzantine period, during the time of the Knights, the castle also offered the inhabitants of the surrounding villages protection against enemy attacks.
It had rectangular bulwarks and two massive towers. Its only gate leads to the south-east corner tower. Two construction stages can be distinguished. Inside the castle there are preserved ruins of buildings and two tanks. This is the place where a significant inscription dated 1473 and referring to the activity of Roman Catholic priests in the area comes from.
The castle is easily accessible, and a number of signs direct the visitors all over the route on the winding mountain. It is also easily seen from the valley below and the main road. If you are there by car, just follow the signs and make sure you park your vehicle in the designated parking area.
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.
