I visited these large barrows whilst visiting the row of 5 to the north. They are much bigger than the northern set, the three still in exitence are sized as follows:
6- 36 yards by 8 feet high 7- 40 yards by 11 feet high
8- 36 yards by 71/2 feet high
9- destroyed.
9a- virtually destroyed.
Dimensions are taken from L.V.Grinsell – Somerset Barrows Part1 – South and West.
