Schloss Gutenberg stands on a prominent rock. IT was founded by Luitold III of Waldstein, who moved into the castle in 1185. The castle has belonged to the Stubenberg family since 1288. The oldest section from the 12th century was supplemented by a 2-story bailey that is protected by two moats. The outer moat is bridged today, the inner was filled in. The castle was remodeled and expanded, mixing the medieval style with Renaissance elements. An irregular four-story building complex with an almost pentagonal footprint and similarly pentagonal courtyard. The rustic gate faces south.
The southwest corner with the Chapel of Saint Pancras constitutes the oldest section of the castle. The chapel, originally constructed over three stories like a tower, with galleries in both upper stories, was dedicated in 1365. Entry is on the first gallery with frescoes that were isolated by the later addition of a dome. The frescoes from the second half of the 14th century show St. Alfa, St. James the Elder, the Martyrs of Ten Thousand, St. George, and the Caravan of the Three Kings. The Romanesque window behind the altar now has modern glass.
A chapel from about 1721 stands on the access road. The second chapel is from the third quarter of the 18th century. Two stone figures, St. Anna and St. John Nepomuk, originally from Schloss Wieden at Kapfenberg, also stand along the access road. Both are by Veit Königer, from about 1770.
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.
