Wildenstein Castle consists of a residential and fortified tower. Unlike other castles of its kind, the tower remained intact after losing its military and residential functions in the 15th and 17th centuries. The history of castle dates back to the 13th century. In 1293 Heinrich von Eptingen took the name von Wildenstein. Under his son Gottfrid Wildenstein defended the castle against the the Bern and Solothurn armies in 1334. In 1995, the canton of Basel-Landschaft acquired the Wildenstein, and today there are regular cultural events.
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.
