The Ground Plan and description of Manor Farm Moat in Huntingdonshire
This is almost circular moat, at Manor Farm in Southoe, of 300 ft. diameter. Outside the moat, on the south side, is a sunk space, 100 ft. by 40 ft. and 4 ft. 6 in. deep; and at the south-west a circular mound 32 ft. diameter. Some 170 ft. away on the west, and about 70 ft. on the north-west, is a large moat or fosse with a considerable bank, apparently serving as an outer defence on that side; it is very wide at the north-west corner, and has an extension of 220 ft. in length towards the north.
