Helme Caves
Helme Caves are a group of artificial caves carved into the Burtnieki sandstone cliffs beneath the ruins of Helme Castle in Tõrva Parish, Valga County, Estonia. The caves were first formed by natural spring erosion and were later modified and expanded by human activity. The cave system historically consisted of seven chambers, with passages reaching up to 3 meters in height and extending approximately 20 to 30 meters into the hillside. They are believed to have been used for practical purposes such as shelter and storage during earlier periods.
