Wiesberg Castle stands above the Trisanna River, where the Paznaun Valley leads into the Stanzer Valley. The castle was probably built in the 13th century. From the end of the 14th century until 1411, the castle was owned by the Rottenberger family. From 1770 until 1840, the castle was owned by the Dukes of Wolkenstein. Near the castle in 1809 several hundred local militia defended the area against Bavarian and French troops. Today Schloss Wiesberg is a privately held property and is not open to the public. The castle can be seen from the Silvretta-Hochalpenstraße.
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.
