Globular Amphora culture
Ewald Schuldt realised that the Funnelbeaker and Globular Amphora cultures buried their dead in the main chamber hall ("Kammerdiele") or a secondary hall and then filled the graves in. He thus concluded that there were close links between the builders of the megalithic sites, the Funnelbeaker culture and members of the Globular Amphora culture. By contrast, the burials of the Single Grave culture always took place in the upper part of the earth fill ("Füllboden") of the grave chamber and access to the site was generally achieved by force from above. This suggested that they were carried out by strangers who no longer had any connexion with the burial concept of the builders of the megalithic sites.
