Sobowidz Castle was built in the second half of 14th century by the Teutonic Order. During the Polish–Lithuanian–Teutonic War it was conquered by Polish, but later returned to Teutonic Order. The castle was mainly destroyed in 1454 when Teutonic Knights surrended. In the 16th century the castle was rebuilt to Governor palace, but it was again destroyed by Swedish army in the 17th century and demolished in 19th century. The current red-brick building was built after that. Today Gothic basement, moat and parts of the wall remain of medieval castle.
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.
