Surrounded by vineyards, Château du Wineck stands on a granitic rocky outcrop in Katzenthal. It was constructed during the 13th and 14th centuries.
The keep is 20 metres high with an almost square plan. A modern external staircase on the western side of the keep gives access to the first floor via a 19th-century entrance. A modern interior staircase gives access to higher levels. Originally, the second floor was entered via a high door in gothic arch off a walkway in the south wall (today, a wooden balcony) leading to the roof of the residence to the west of the keep. On the third floor, to the north, a latrine remains. In the south-eastern corner of the roof there is a gargoyle. The original parapet has been restored. The horseshoe shaped enceinte enclosed the keep from the north and parts of its round walk still exists. To the west of the keep was the residence; to the east the stables. A second enceinte opposite the castle sheltered the lower courtyard. The moat surrounding the castle was cut into rock in the north.
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.
