In Eliášské údolí or Eliastal (the Elias valley) the remnants of silver ore mining in the 16th to 19th centuries are uniquely combined with those of the uranium mining activities in the second half of the 20th century. The relics of the oldest mining era can be most easily recognised on the road between Nove Mesto and Abertamy. Here, dozens of heaps and sink-holes mirror the routes of underground silver seams. In the middle of the 16th century, the Heinzenteich pond (now Horký rybník) was created to provide water for the mining works. After the Second World War, the central part of the Elias valley in particular changed significantly as a result of uranium mining. The tremendous extent of the underground mining is evidenced by the enormous heaps for the Eduard, Jiřina, and Eva shafts, and those higher up the valley belonging to the Rovnost, 14, and Adam shafts.
