 * Sausmarez Windmill, St. Martin


 * Vale Windmill

A windmill was standing on this site in 1847. Vale Windmill is a five-storey tower mill that was built in 1850. Photographs show it to have had four patent sails mounted in a canister, and an ogee cap similar in shape to those found in Suffolk, winded by a fantail. The mill had a stage at first floor level. It was converted into an artillery observation post by the Germans during the Second World War. This work entailed a three-storey extension being built on the mill tower, making it 21 m high overall. The windmill featured on a 2p postage due stamp issued by the Guernsey post office in 1982.



Alderney
There is a record of a windmill owned by the King before 1242 on The Blaye.

Alderney had a windmill built in 1560.

Sark

 * Sark Windmill

Sark Windmill was built in 1571 at the seigneur's expense. It is situated on the highest point on Sark (114 metres or 374 feet above sea level), called Le Moulin after the windmill. It is a three-storey tower mill with an ogee cap. In the early 19th century the mill was burned by Sark tenants protesting against the seigneurial system there, but it was later refitted with new machinery and heightened. It was working by wind until 1917 although the sails were removed during World War I. It was used as an observation tower during the German occupation. The mill had four double patent sails, and was winded by a fantail. The mill featured on the 1971 and 1977 2p coins issued by Guernsey.

Little Sark Windmill was a tower mill. The tower remains today, mostly covered in ivy.
