Rauheneck Castle is a ruined administrative castle of the Bishopric of Würzburg. According to legend, it had been built around 1180 by the Rauheneck family. They later allied with other noble families and placed their estates under the Bishopric of Würzburg. After the family's decline, the castle passed through various hands, including the Marschalks, before returning to the Bishopric. In 1829, the Barons of Rotenhan acquired the castle, but it has since fallen into decay. Recent efforts have begun to restore and preserve the 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.
