A Chamber Tumulus is a large megalithic construct found in certain early neolithic societies. They have been uncovered along the Atlantic coastline in northern Europe, in countries such as France, Spain, Portugal and Ireland. These megaliths have also been found in southern Scandinavia, primarily in Scania and Falbygden. In Denmark there are numerous older megaliths, less advanced that the versions elsewhere, thought to be monuments marking communal burial places.
