The discovery of a Neolithic dolmen in Switzerland with inhumations, dating between 3500 and 3000 BCE, was an exceptional finding. To provide best conditions for subsequent studies on the archaeological remains our interdisciplinary team decided to apply 3D documentation. Depending on different factors, two scanning systems with four scanners and photogrammetry were applied and the obtained data was combined. Detailed excavation plans and simultaneously a reduction of excavation time without loss of information were the result. A virtual animation of the dolmen in its reconstructed ancient appearance combined with the context of the grave goods was created. The 3D documentation provided initial data for anthropological and paleogenetic analyses. The individuals buried in the dolmen might provide novel information to the Neolithic research of central Europe. Additionally, with the help of the 3D data, the dolmen was rebuilt to make this archaeological heritage accessible to the public.
