West Bower Manor (also known as Durleigh Manor), which stands on the shore of the reservoir, is all that remains of a large manorial property, the majority of which has been demolished. Parts of the building date from the 15th century though the core of the fabric may even be earlier, further parts were built in the 17th and 19th centuries.
The principal surviving element from the Medieval manor is the gatehouse. This has been extensively restored, but is a good example of a former courtyard gatehouse with a pair of faceted turrets on either side of the former entrance passageway.
