Hückeswagen Castle was first mentioned in 1189. In 1260 the county Hückeswagen was disposed to the counts Berg, and the Hückeswagener counts moved to Moravia. In the future the castle of the countess Margarete von Hochstaden served as a widow's seat. To constant Verpfändungen of Hückeswagen during the following centuries the name changed in 1397 into castle. During the following centuries the castle was mostly in a bad state, until it reached in 1884 at first partially in the possession of the town. Today it accommodates municipal offices and a museum of local history.
One of the most striking components of the arrangement is the donjon which is also called 'scoundrel's tower'. He was probably established in the first third of the 13th century. The oldest view of the castle of Erich Philipp Ploennies at the beginning of the 18th century shows the tower with 23 metres substantially higher than today. The reduction on two floors occurred at rebuilding and protection work at the beginning of the 19th century.
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.
