The imposing two-part moated Burg Gudenau is the largest castle in the municipality of Wachtberg. Its grounds are a special feature, as they are the only Baroque garden under private ownership in the Rhineland.
The castle stands in a flood plain at the foot of Villip, at the confluence of the Godesberg and Arzdorf streams. Built in the early 13th century, the main castle with four wings was extended in about 1560 with extensive grounds to the rear. Additions were made here such as bays and curved roofs. In the 17th century the remarkable gardens were created under an Italian influence. A second lower castle with its imposing five-storey gate tower, a slate hipped roof and an eight-sided clock tower feature on the visible side of the castle. The main castle also possesses a Gothic bay and a round corner tower with a pointed slate dome, whilst the remaining three corner towers have Baroque domes.
The castle is under private ownership.
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.
