Once the domicile of the Counts of Wertheim the castle (extended during 15th to 17th centuries) is one of the most picturesque ruins in Germany with a deep moat and impressive bulwark. In 1618 the castle was partly destroyed by an explosion; during the Thirty Years' War in 1634 and 1647 it was under heavy fire. Today the castle is owned by the Community of Wertheim growing into a more and more attractive setting for cultural 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.
