Lom Šífr, Flooded slate quarry in Svobodné Heřmanice, Czech Republic.
Lom Šífr is a flooded slate quarry in Svobodné Heřmanice with clear water and significant depth. The pit extends horizontally across large areas and features different zones that offer varying water depths.
Slate extraction ended decades ago and the quarry naturally filled with water over time. This transformation converted the industrial site into a location for water activities and diving.
Divers use the water regularly for training and technical practice, making this place important for the local diving community. The clear water also attracts swimmers and snorkelers who spend time exploring the site.
The northern area features a sandy beach with easy water access, parking, and a pier for visitors. These facilities make it convenient to put on diving equipment and prepare for water activities.
A submerged cabin called Permon hangs from iron wires at considerable depth and was used for underwater research. This unusual installation shows the history of scientific experiments conducted at this location.
