The Hossa Värikallio rock paintings are amongst the largest prehistoric rock paintings in Finland. The pictures on the rock wall rising from Lake Somerjärvi were painted in the Stone Age, i.e. about 3,500 - 4,500 years ago.
Paintings were painted from a boat or when standing on the ice of the lake. On the surface of the rock wall there are 61 separate figures depicting scenes of hunting and shamanic rituals. The paintings have probably been used for marking a route or describing events.
Värikallio is accessible all year round. In summer there is a trail leading to the paintings, and an observation platform has been built in front of the cliffs. In winter there is a skiing trail to the cliffs and a snowmobile trail nearby. The access to the paintings is free-of-charge. Theme guiding for groups is subject to a charge.
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.
