Sandstone, characterized by nuanced shades of blue and green, is quarried along the Haarstrang. The many uses of this stone, from architectural design to natural stone walls, are the reason for its international relevance. The Anröchter Stone Museum and a sea container platform above the former Drewer quarry, which serves as a viewing point, make it possible to gain a comprehensive understanding of the culture of stone mining and its influence on the local natural and cultural landscape.
