Haulage drift with a bench in Prokopské údolí
Short and straight through haulage drift in Prokopské údolí ("St.Prokop's valley") belongs to neighboring Prokop quarry. Other remains of local underground including former nazi factory "Eulalie" or "Kali I", where ČKD factory was manufacturing engine parts for Jagdpanzer 389(t) "Hetzer" tank during World War II., and still undocumented karst caves are unfortunately included in well-guarded military area unaccessible for a civillian.
