The "Herzogsgrab" in the Mönchguter Forst is one of the numerous mound graves preserved on the Island of Rügen.
Investigations in the 1920s, but also the systematic excavation by Dr. Ingeburg Nilius of the Chair of Prehistory and Early History of the University of Greifswald in 1960 at the Funnel Beaker Period megalithic grave yielded extensive find material. These include amber beads, remains of about 50 ceramic vessels, stone axes and hatchets, and cross-cut arrowheads, as well as skeletal remains of at least 20 individuals. In the "Duke's Grave", a large dolmen with a windbreak and a trapezoidal mound bed, a later burial from the Bronze Age could be proven.
