The earliest ritual use of this site is most likely to have been the construction of the long barrow between 3400
and 3000BC. Related to it, and dating from roughly the same time, is an enclosure used for preparing the dead for
burial.
The body was left in the open air and progressively cleaned of all flesh by the wind and the birds, leaving the
bones ready for the burial. This process of de-fleshing is known as 'excarnation'. Despite its purpose, excavations
in 1959 failed to discover any human remains in this area.
