Basaltsteinbrüche Hühnerberg und Eudenberg / Tongrube Eudenbach

The protected zone encompasses 144 hectares of basalt quarries, clay pits, and small water bodies across two distinct areas near Eudenbach.

Mining operations at Hühnerberg began in the late 19th century, with Willmeroth and Hühnerberg quarries merging into a single operation in 1976.

The area maintains geological importance as it demonstrates the evolution of mining techniques from manual labor to modern mechanized extraction methods.

Weekly controlled explosions extract approximately 30,000 tons of basalt using 40 kilograms of explosives under current operational procedures.

The quarries provide essential habitats for yellow-bellied toads and great crested newts, with over 50 specimens recorded in the Eudenberg pond.
