The Hřebečná mining district is an exceptional witness to 400 years of the extraction of tin ore from the 16th to the 20th century. It bears excellent evidence of mining tin ore (cassiterite) from steep greisen veins crosscutting the surrounding granites. The well-preserved mining landscape contains a large number of both aboveground and underground mining monuments, the extent and state of conservation of which lends them supra-regional importance. Among the most significant of them are the opencast of the Rote Grube (Red pit), the Schnepp sink-hole and especially the Mauritius mine, the biggest and deepest tin mine in the Czech part of the Ore Mountains which was declared national cultural property in 2014.
