The museum-castle Grimmenstein is the most famous sight of the village of the same name. The building consists of a so-called high castle on the rock and a hillside castle below. The name of the castle dates back to the 12th century, but its foundations and parts of the masonry are much older. Some sources point to a much older history of the castle, for example, part of the preserved keep is said to date back to a Roman watchtower around 2,000 years old. After years of decay, it has been undergoing extensive renovation by the Grimmenstein family since 2014.
The closest public parking is the Asfinag parking lot in the valley, from which a slow train departs every hour during opening hours. To linger until the next guided tour of the castle, you can enjoy the magnificent panorama of the Buckligen Welt from the terrace and fortify yourself with snacks, homemade pastries and drinks.
The destination is also popular as a location for children's birthday parties and private celebrations. The castle is heated and can be used for events all year round.
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.
