A moat and fishpond sited on a gentle south facing slope. It comprises a sub-rectangular moat of unusually large size enclosing a late medieval manor house, with a large fishpond immediately to the north. The moat is 74 metres wide at its widest point in the south west corner, and 9 metres at its narrowest, measuring between 1.5 metres and 2 metres in depth. The moat surrounds an island measuring 106 metres north-south and 56 metres east-west. The fishpond to the north is roughly triangular, measuring 140 metres north-south with a maximum width of 42 metres and a depth of between 2 metres and 3 metres. A house is believed to have stood on the island from before 1256, when a licence was granted for a chapel to be erected at Wanswell. The core of the existing manor house, which is a Grade I Listed Building, and which stands at the northern end of the island, is an hall house of around 1450-1460 with additions of the early 16th and early 17th century date. The core is constructed from part rubble stone and part coursed and dressed stone. The 17th century wing is faced in roughcast with long and short flush quoins. The roof is of Cotswold stone slate except for the range to the north of the hall which has a slate roof. Scheduled.
