Two remarkable parallel earthen long barrows were built at Barkaer in Jutland in the Neolithic. Originally interpreted as long houses built on the site of an earlier settlement, Barkaer is now recognized as a ritual site.
The two barrows were oriented east-west, were 20-26 ft (6-8 m) wide and 280-300 ft (85-90 m) long and were placed 33 ft (10 m) apart. Each had a timber facade at the eastern end. The interior structures were subdivided by twenty-nine and twenty-one wicker partitions respectively, and there were also the remains of many wooden posts.
Each barrow contained two graves close to the eastern end. A double pair of post holes produced fifty-nine amber beads, two pieces of copper and a flask.
In other parts of the structure were discovered burnt cattle bones, tools and pottery.
