The construction of the Przezmark castle started at the beginning of the 1300s continued until c. 1350. In the next centuries the stronghold was repeatedly converted because it was adjusted to new functions: the seat of a commune head, a prosecuting attorney and a convent. Since the beginning of the 16th century the castle belonged to the bishops of Pomesania as to later come into hands of the families of von Egmon and von Verdte. After the period of the private owners, came the period, in which the stronghold performed the function of the seat of the offices to finally decline and to be disassembled in the 18th century The first of the old names of the castle suggests that before the Teutonic times there existed the Prussian merchant settlement. The tower that has survived till our time emerged around 1329 and is called the Prisoner-Of-War Tower.
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.
