This barrow could possibly be the shortest known bank barrow. In David Field’s excellent book Earthen Long Barrows he refers to a Bradford Peverell bank barrow of 64 metres in length. Another candidate could possibly be the long barrow called Red Barn, which is equally close to Bradford Peverell. However he provides no grid reference for it, I will probably have to write him a letter to find out.
Grinsell says this is 150 feet long, 60 – 90 feet wide and 4 feet in height.
