The Astuvansalmi rock paintings are a 3km walk away from a parking area in Ristiina, Finland. It is only a tiny path that leads to them (no wheel chair access), and the place itself is not that special but these rock paintings are the largest ones found in Scandinavia. The paintings are on the rock on the right – a rock that has the silhouette of a face.
It is impressive that the paintings have survived about 5000 years! Wonder what the paint was made of? Anyone who knows?
Wikipedia can inform you more about motifs etc

Okay, you have got me going there, now. What is the paint made of? Someone must have studied this question…
