Kronburg Castle was first time mentioned in 1227. In the 13th and 14th centuries it changed hands several times between Hohenstaufen and Habsburg vassals. The castle was restored in 1490-1536 by Rechberg family. In 1524 it was occupied by revolting peasants and in 1625-1627 it was passed to Johann Eustach von Westernach.
Kronburg was conquered and partially demolished by French army during the War of the Spanish Succession (1703) and rebuilt in residential style in 1707. Today the castle is owned by the von Vequel-Westernach family and hosts weddings and other events.
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.
