The Castello di Naro was built on top of a hill in the 14th century by the Chiaramonte family. The complex includes walls with battlements, a square tower built by Frederick II of Aragon and the imposing 'mass of the male'. On the east side there are two mullioned Gothic windows that illuminate the great 'Hall of the Prince', which is located on the first floor of the tower. The portal is flanked by two rectangular bastions. The massive outer walls are interspersed with two cylindrical towers and two square towers.
Inside the walls there is a large courtyard, which housed the accommodation of the garrison, the chapel and the stables, and in the case of attack offered refuge to local farmers.
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.
