The sandstone caves are the result of hand-mining glass sand during 1922–1966.
The area of the ancient Piusa River valley that is between the villages of Vana-Vastseliina and Ignasõ is around 15 km long, features some substantial rapids, and offers a view of beautiful Devonian period cliffs. The largest, Härma müür, is 43 metres high and is the highest sandstone cliff in Estonia. There are caves from old mines in the village of Piusa. A small part of the mines, which have tunnels that are more than 10 km long in all, has been tured into a local museum.
