The area of the former red pit mine represents the largest early-modern system of opencast mines and shaft depressions in the Ore Mountains. The pits account for the largest ones of its kind in Czech Republic and assumedly in an international scale too. They provide a prominent example of extracting tin ore from wide greisen zones which were first mined from shallow shafts and subsequently by opencast mining from the early 16th to the mid-18th centuries. The main, elliptically elongated, depression is 230 m long, around 30 m wide and over 20 m deep. To this depression, another one is linked and is approximately 120 m in length.
