Area: 50 ha
Material: black coal by tree horsetails, ferns and lycophytes in marshes of the the Krkonoše Piedmont Basin in the Lower Paleozoic period

 

Coal was discovered in Lampertice near Žacléř in 1570. The Jan Šverma Mine was established in 1950 by merging several existing mining pits. Mining ended in 1992, subsequently the mining areas (a total of 60 km of tunnels) were filled with a self-sealing mixture of sludge from industrial sewage treatment plants and power plant fly ash. Reclamation of the spoil tip (2005–2007) included creating etages which were grassed over. At present, grasslands are mown, in some parts knotweed and and Wood Small-reed are spreading.  Southern slope has a potential for more thermophilous vegetation. In some places there is early succession woody plants overgrowth. The spoil tip is used for sports (cycling, cross-country running). The mine is a monument of deep coal mining in eastern Bohemia and since 2011 it has been classified as a cultural monument of the Czech Republic. Since 2015 there is a mining museum.
