Glasebach Pit

The Glasebach Pit (German: Grube Glasebach) is a mining museum and former pit in the Harz fluorspar mining area near Straßberg in the German state of Saxony-Anhalt.

It is run by the East Harz Mining Society (Montanverein Ostharz e. V.).

At Heidelberg north of Straßberg, fluorite and silver were won and processed at a smeltery on the site on behalf of the counts of Stolberg.

There was also flourishing mining activity on the Glasebach stream, which formed the boundary between the County of Stolberg and the Principality of Anhalt-Bernburg.

Various mining artefacts are displayed in the museum, including the old wooden drainage outlet (Grundablass) of the Lower Kilian Dam (one of the oldest dams in Germany), salvaged in 1990 during renovations, after it had undergone long-term conservation work by the Harzwasserwerken in Clausthal-Zellerfeld.
