Snezhanka Cave at the town of Peshtera, Pazardjik district, in the Rhodope Mountains. Space 3200 sq m. Calcite freaks. Cultural remains of the Thracian tribe Bessi that inhabited that part of the Rhodopes some 2000 years ago can be seen in one of the halls. A spiral-shaped bronze fibula (pin), fragments of hand-made pottery (without using a potter's wheel) are some of the finds dated to the 6th-4th centuries BC.
A round hearth 4 m in diameter and bones of wild and domesticated animals that the cave dwellers used in their diet has survived. The cave and 156.2 ha of land around the cave became a natural sight in 1961.
