Staufeneck Castle was built in the 12th century by Burggrafen von Staufeneck. In the year 1307 the castle went into the ownership of the Erzstift Salzburg, under whom it served as one of the maintenance courts in Rupertiwinkel from 1365 to 1805. In 1503, the castle was under Archbishop Leonhard von Keutschach who fundamentally transformed it, giving it its present appearance. Since 1894, the castle has been under private ownership. In the 20th ceuntry, the castle housed a museum. After a complete renovation, it is once again inhabited.
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.
