At the end of the 14th century, Teutonic Knights built a castle in Ryn, serving as a base for fighting with the Lithuanians. Until 1525, the castle was the seat of the commander. After two years of the construction of the castle, then the Grand Master of the Order Winrich von Kniprode arrived in Ryn to inspect and take over the castle, and returned to the Malbork by waterway. In 1723 Ryn received city rights granted by the Prussian King Frederick William I and in 1853 the castle was converted into a prison. Since July 2006, the castle operates as a hotel.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.
