Międyrzecz Castle was built around 1350 by Casimir III the Great in the place of a former gord from the second half of the ninth century, located on a small hill in between two floodplains of the Obra and Paklica Rivers.
Due to the location of the stronghold, the castle was expanded and modernised, although that caste itself did not go through any major battles in the medieval times. In 1474, King Matthias Corvinus of Hungary took over the castle. In 1520, the castle was heavily damaged by the Teutonic Order during the war with Poland, after which the castle was modernised and in 1574 two bastions were built around the castle.
In 1655, the castle was destroyed by the Swedes. In the first half of the eighteenth century the castle was so damaged that even after reconstruction the castle was not able to be used. After the Second Partition of Poland the Prussian forces gave the castle to a Prussian family. The interior of the castle was used as a warehouse and the top floors for a winery.
Since 1945 the castle is used to house a museum. In the years of 1954 to 1958 a number of archaeological excavations were carried out. In the 1950s and 1960s the castle was renovated and stopped the castle from becoming a ruin. The gatehouse and nearby living quarters were reconstructed.
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.
