A sensational archaeological discovery has been made in canton Bern: a community grave dating back 5,000 years, containing 30 bodies and Stone Age artifacts. It is the first intact burial chamber to be found north of the alps. A team from Swiss television's flagship science programme, Einstein, has been following the archaeologists as they continue their research on the so-called dolmen or megalithic tomb.
