The Bonstorf Barrows are the remains of a much larger barrow cemetery on the Lüneburg Heath in north Germany dating to the late Neolithic or early Bronze Age. They are located east of the village of Bonstorf, part of the municipality of Hermannsburg in the Lower Saxon district of Celle. The site comprises six, closely packed burial mounds or barrows.
The largest barrow was located originally in a field, but due to its vulnerable location it was dug out in 1973 and reconstructed nearby. Of interest are the internal stones which were found in the burial mound. The barrow was surrounded by a stone circle.
