Belas Knap 
Belas Knap, a neolithic chambered long barrow in the Cotswolds, UK.
A well presented example of a neolithic long barrow, subject to excavations in 1863-5 and again 1928-30 after which the barrow was restored by the Ministry of Works to the appearance that we see today.
Situated on close to the crest of a hill with panoramic views particularly to the north and east the barrow is trapezoidal in shape and about 55metres long and orientated roughly north-south.
Radiocarbon dating of bones recovered from excavations at Belas Knap indicate that it was in use as a burial monument from 4000-3700BC.
