Lengefeld Lime Works

The Lengefeld Lime Works () is a limestone mine southwest of Lengefeld in the Saxon town of Pockau-Lengefeld in the Ore Mountains. It is the last mine in Saxony and the last mine on the German side of the Ore Mountains that still transports men and materials into the mine up and down vertical shafts.
Geology of the deposit.
The Lengefeld deposit is located not far from the B 101 road, in the wood between the Heinzebank and Pockau. The only element of economic value is dolomitic marble, which is categorized lithostratigraphically as part of the Raschau Formation within the Keilberg Group. The material immediately surrounding the deposit comprises Lower Cambrian rock of the Raschau sequence, about 530 to 540 million years old. Feldspar-bearing muscovite mica-schist forms the basis of this sequence in which thin lenses of amphibolite are interspersed. The stratum of dolomitic marble has an average thickness of 50 to 90 metres. Host rocks include garnet-bearing and quartzitic muscovite mica-schist as well as interleaved strata of quartzite schist ("Quarzitschiefer"). As a result of the Variscan mountain building the once compact body of marble was split into five blocks known as the "Altes Lager" ("Old Deposit"), "Neues Lager" ("New Deposit), "Tiefes Lager" ("Deep Deposit"), "Lößnitz-Lager" ("Lößnitz Deposit") and "Weißer Ofen" ("White Kiln").
History.
The mining of lime from this deposit was first mentioned in a deed of enfeoffment dated 1528. This was a result of lease agreements or was a fiscal deed produced under the direction of the Royal Saxon Forestry Offices. In 1567, the existence of a quarry and two kilns is recorded in a deed of sale by the Barony of Rauenstein to Prince-Elector Augustus. 
The rated quantity of lime produced per firing was 280 tons for one of the kilns, and 260 tons for the others. Lime from Lengefeld was used "inter alia" by the architect ("Baumeister"), Hans Irmisch, for the construction of Freudenstein Castle in Freiberg.
In the final years of the 17th century, the Scheibenberg pastor and chronicler, Christian Lehmann, praised the production of lime around Lengefeld:
