Historical records of ore mining in the Ore Mountains begin in 1168, when silver ores were discovered in the vicinity of today's Freiberg. More than 800 years of mining history of the Ore Mountains are based on this discovery.

Markus-Semmler-Stolln (adit) was started in 1503 as the main drainage adit of Schneeberg’s silver and cobalt mines. It was enlarged to become the principal adit in the Schlema-Hartenstein District and since 1946 it served as the main drainage adit of the Uranium Mining Landscape, its total catchment lengths totalling over 220 km. It is Germany’s longest serving adit in continuous function, and its portal is included in the nominated property.
