The Buskam, also Buhskam or Buskamen is a large boulder 325 meters off the coast of Göhren, Rügen, northern Germany. Boulders (German: Findlinge) had been scattered all over northern Germany by the glaciers of the Ice Age, but usually are much smaller. The Buskam has a volume of about 600 m³, a circumference of about 40 meters, and weighs about 1,600 tons. A third of it (206 m³) is above the water surface.
Cavities in the rock indicate that the Buskam was used as a ritual place in prehistory, when such caved rocks were commonly used for ritual sacrifice. An iron crucifix was attached to it after introduction of Christianity.
According to local legends, the Buskamen is the site where witches dance during Walpurgis Night, also mermaids are supposed to often dance on the rock.
