No one knows for sure the origin of the sacrificial stone.
According to legend, it originates from Utanmyra on Sollerön where it has probably been for thousands of years. For some reason, it ended up in the shack Gesunda. Eventually it was moved here out into the woods between Gesunda village and Gesundaberget.
The sacrificial stone is a sandstone slab with bowl pits. The sandstone slab is 1.3 m long and 1.05 m wide. In its smooth top there are about 25 bowl-shaped depressions, so-called bowl pits, which are knocked out with pebbles.
It is difficult to date bowl pits, but some of Dalarna's about 20 places with bowl pits can be 2,000–4,000 years old, ie. from the Peasant Stone Age to the end of the Iron Age.
Bowl pit stones are often called sacrificial stones and most are located on mountain pastures. In folklore, the stones are called river mills. They have probably played an important role in connection with the fertility cult. A theory is also that they sacrificed a few grains of grain or some flour in the pits to get a safe ride over open water or to get security along paths or in mountain huts.
