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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
