Mayen basalt was historically exported across Europe because of its unique hardness and porous structure, ideal for grinding grain.
The site contains remnants of 'millstone paths' where finished heavy stones were transported manually or by horse-drawn wagons.
Geological evidence of prehistoric volcanic activity is physically visible in the exposed basalt rock layers within the quarry.
The park serves as a Geopark information center for the Vulkan- und Osteifel region.
Several exhibits demonstrate how workers shaped basalt into functional objects using only manual iron chisels and hammers.
The quarry layout reflects the transition from small-scale manual extraction to industrialized, steam-powered mining in the 19th century.
Erlebniswelten Grubenfeld is an industrial heritage park and outdoor museum located in a former basalt quarry in Mayen. It documents 7,000 years of mining history, focusing specifically on the extraction of basalt lava used to create millstones. The site spans the original quarry floor, where visitors can walk through historical extraction sites and industrial workshops. It serves as a decentralized part of the Eifel Museum, integrating geological history with the technical evolution of mining equipment. Interactive exhibits allow visitors to understand the strenuous labor conditions and the geological formation of the Eifel volcanic region. The site features original heavy machinery, historical cranes, and stone processing tools preserved in their authentic work environment.
From the upper viewing platforms overlooking the deep, sunken basalt quarry pits.
Wear sturdy, closed-toe footwear suitable for uneven, gravelly quarry terrain.
Bring a light jacket as temperatures in the shaded quarry sections are significantly cooler than the surrounding area.
Download the site's digital guide or map before arrival, as cell service can be intermittent in the deeper quarry pits.
Do not attempt to walk the entire perimeter if you have mobility issues, as the terrain includes steep, unpaved inclines.
Closed on Mondays throughout the main season; typically closed during winter months from November to March.
Stay on marked paths to avoid tripping hazards on loose volcanic rock; do not climb on historical machinery.
