You can find out more about the cult of the dead in Denmark's Peasant Stone Age around 5200 years ago. Building a large stone grave required some experience and was probably done by specialists. Traces of wooden construction suggest that some type of towing crane was used to move the large stones. The deceased found their final resting place in the burial chamber. However, the Sulkendrup Chamber collapsed very early and had to be repaired. Although it was unstable afterwards, it was still used as a communal grave for the rural population. Hundreds of years later, the Bronze Age people dug a grave on top of the stone grave and built a mound over it. The Iron Age people also buried their dead in the hill. It was used for burials for more than 3,000 years. The first archaeological excavations took place in 1919. The grave was closed for a long time because of the danger of collapse. From 2013 to 2014 the burial mound was secured and restored. Today it is accessible again.
