This is just south of the road from Warminster to the lost village of Imber. It is either a twin barrow or two contiguous barrows and is part of a group of five following the ridge line. It’s national monument number is 10100, and is on the restricted firing range on Salisbury plain.
Just been looking at Imber and the Imber Bus Run, something I'd never heard of, fascinating. Nice to see you Mike.
