The Great dolmen of Dwasieden (German: Großdolmen von Dwasieden), is a great dolmen in the borough of Sassnitz, on the Jasmund peninsula of Germany's largest island, Rügen. It was excavated in 1970 by Ewald Schuldt and is designated a Sprockhoff No. 472. The megalithic site of the Funnelbeaker culture (TBK) was constructed between 3500 and 2800 BC.
According to Ingrid Schmidt, "Neolithic monuments are an expression of the culture and ideology of New Stone Age communities. Their creation and function are features of social development".[1] The site was painted in 1806 by the Greifswald-born artist, Caspar David Friedrich (1774–1840). His diagrams and sketches are kept in the Ashmolean Museum of Art & Archaeology at Oxford.
