The Riesenstein (English: giant's stone) is a megalith or menhir, which is situated close to the village of Wolfershausen. It is the largest megalith in the district of Schwalm-Eder-Kreis, Hesse, Germany.
The Riesenstein is located 1.14 km (0.71 mi) directly north of the village of Wolfershausen. It can be reached from a tarmacked road north of the railway bridge, where it is signposted. It is located on the south-eastern corner of a small woodland. The megalith is also close to the eastern bank of the Eder River, which is just 180 m (590 ft) away (over the railway).
Riesenstein is composed of Neogene Miocene (from 23 million years ago to 8 million years ago) quartzite. In contrast to quartzites produced by metamorphism, the Tertiary sedimentary quartzites were the product of intense weathering of local Triassic Buntsandstein sandstones in a tropical climate. This entailed bleaching of sandstone and silicification by movement of silica-saturated groundwater through the strata. Consequently, the rock is practically made completely of quartz, with very little porosity.
