The Albericke quarries, today a preserved natural monument, supplied limestone and slaked lime in the 19th century. An old lime kiln, in which a museum called Vapenka was opened recently, can be seen in Horni Alberice near the road to Lysecinska chalet.
The quarries are home to many rare calcareous plants and animal species, and the remains of a lime factory with a small underground karst have been preserved here. The abandoned Bischof quarry is quite deep, with the temperature hovering around 7°C even in hot summers. The end of the quarry is an entrance to Albericka Cave, a karst cave containing a large underground lake with a depth of approx. 15 m. Krakonosova Cave, located closer to the Polish border, is of approximately the same length.
