The 65 rock paintings of Astuvansalmi are the largest found in the whole of Scandinavia. The oldest paintings are made 3000 - 2500 BC. They are located at the highest level (about 11 metres). The water level changed very fast about 2,5 metres with the landslide of Vuoksi. Later on the level slowly went down 8 metres to its present level. All the later paintings have been made from boats during the different historical water-levels. The form is clearly visible during wintertime while viewed from the ice of the lake.
The Astuvansalmi rock paintings contain the following pictures: 18-20 elk, about as many human figures, tens of hands and animal tracks, 8-9 boats, geometrical figures and pictures that are thought to show a fish and a dog. The paintings could have a link to the Siberian and North European shamanistic tradition.
Other archeological artefacts have also been found on the site at the bottom of the lake, for example small amber statuettes of old gods, animal jewellery and arrowheads.
Astuvansalmi rock paintings are submitted to the Tentative List of UNESCO World Heritage Centre.
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.
