Nearby, the Giershagen Geological Garden can be visited with almost 40 different types of rock from the 3 geological eras of Devonian, Carboniferous and Permian on the geological ground plan of the Giershagen district. The motto of this unique project is: "Stones tell their story". There is also an accompanying brochure. The stones are between 20,000 and 400 million years old. Among them are some very special specimens. All the stones are from the district of Giershagen, which lies at the intersection of three major landscapes, the Rhenish Slate Mountains, the Munsterland chalk basin and the Hessian Depression. Definitely worth seeing.

"...The Lanz adit of the Reinhard mine, whose restored adit entrance lies in the Diemel valley, reaches the ore deposit after 670 m. It was driven between 1872 and 1876. As a 40 m level, it is located approximately 19 m below the older Lülingshohler adit (20 m level). Together with an intermediate level (30 m level) and three deep working levels, these two adits form the Reinhard mine workings. The adit system extends to 110 m below the valley floor. Until around 1800, the mine was called "Lülingshohl" (Spatzenloch/Spatzental)...." https://www.bergbauspuren-bredelar.de/b6-grube-reinhard/

After the mine was closed, the dumps were still exploited in the 20th century. When the amusement park was built, the leftovers were then used.
