Schwanenstein, Glacial erratic on northern shore of Jasmund peninsula, Germany.
Schwanenstein is a massive granite boulder located on the northern shore of the Jasmund peninsula, sitting roughly 20 meters from the beach. The formation measures approximately 7 meters long and 5 meters wide, with a weight of about 162 tonnes.
The boulder was carried here by glaciers during the last Ice Age, traveling hundreds of kilometers from its origin before being deposited on this shore. A tragic event in February 1956 marked local history when sudden ice breakage in the Baltic Sea claimed three young lives.
The boulder holds an important place in Lohme's local identity, appearing on the municipality's coat of arms. It connects the community to its natural landscape and maritime heritage.
The boulder is easily accessible from the harbor walkway in Lohme and can be viewed year-round. The best vantage point is along the harbor edge, where you have a clear view and can approach closer during low tide.
A pronounced crevice runs through the western side of the boulder, visibly enlarged by repeated freeze-thaw cycles. This geological feature hints at ongoing change in the rock's structure over coming years.
