History
The mining of lime from this deposit was first mentioned in a deed ofenfeoffment
In the Middle Ages, especially under the European feudal system, feoffment or enfeoffment was the deed by which a person was given land in exchange for a pledge of service. This mechanism was later used to avoid restrictions on the passage of t ...

pastor and chronicler, Christian Lehmann, praised the production of lime around Lengefeld:
:''"By the River Flöha and its tributaries lie 3 noble lime kilns around Lengefeld, which are highly valued, because every year up to 3, 4 or even more times 300 tons of lime can be burned and the value of a ton on the spot is 8 gr."'' (original text: ''„An der Flöhe und ihren Einfällen liegen 3 fürnehme Kalck-Ofen um Lengefeld, die hoch æstimirt werden, dieweil man alle Jahr daselbst zu 3, 4 und auch mehrmahlen iederzeit auf 300 Tonnen Kalck brennen kan, und gilt die Tonne auff der Stelle 8 gr.“'')
In 2016, the company ''Geomin'' closed the mine, because the deposits are exhausted. The processing plant remains in operation for the other quarry
