Kesslerloch

The Kesslerloch is a cave near Thayngen in the canton of Schaffhausen in Switzerland. Located in the Herblingertal valley at the south-eastern foot of the Reiat plateau, the cave is approximately 200 m2 (2, 200 sq ft) in size and divided by a stone pillar. In prehistoric times, reindeer hunters likely used it as a shelter during the summer months between 15,000 and 11,000 years ago (Upper Palaeolithic, Magdalenian culture). Its position in a narrow valley was advantageous for a hunting station, similar to the nearby Petersfels (approximately 15 km [9.3 mi] northeast) near Engen. The cave, along with surrounding forest land and meadows, was placed under state protection in 1902.
