The ruin of Wieladingen Castle lies about 90 metres above the Murg valley. The well-preserved ruin was structurally secured and the 20-meter castle keep was made accessible again with an external spiral staircase leading up to the observation platform with a panoramic panel of the Alps.
The castle wass built in the 12th century and documented first time in 1260.
In the 13th/14th century, the castle was inhabited by squires and knights of Wieladingen. They disappeared from the annals of history by the end of the 14th century.
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.
