1. Situated in the garden of a modern house are the remains of the manorial windmill of Sully. Only the base survives, built of random limestone rubble with sandy mortar and standing to 2.1m high. The circular tower is 5.8m in external diameter with walls 1.3m thick, strongly battered on the outside. It is entered by opposing doorways, 1.1m wide on the outside, narrowing to 0.8m on the inside. A millstone now rests against its inside wall on the W side. It measures 1.07m in diameter and 0.18m thick.

2. A windmill is shown on an historic admiralty chart and so was presumably used for coastal pilotage.
