As prehistoric Britons gathered at Stonehenge, people living in what is now Germany were erecting their own grand monument, a complex of nested circular ditches, pits and rows of posts that were interspersed with the remains of women and children, whom experts believe were human sacrifices.
The German site of Pommelte, which dates back to as early as 2,320 BC, is dotted with 29 shafts containing objects such as shattered jugs, but also skeletons, some of them mutilated, of women and children.
The monument has a number of astronomical alignments with the sun and with to these alignments, together with the burials, many experts believe it was a ritual centre for the ancient people of Germany.
The late Neolithic, early Bronze Age site, which is 377 feet in diameter, has been under reconstruction for several years and has just opened to the public for the first time.
