Daphne du Maurier has said that the fictional Manderley, ancestral home of Maxim de Winter, was based on two actual houses: Menabilly in Cornwall, and Milton Hall in Cambridgeshire. According to du Maurier, Manderley is essentially 'Milton in the setting of Menabilly'.
Menabilly is a Georgian manor house situated on the Gribben peninsula near Fowey on the south coast of Cornwall. It is the family seat of the Rashleighs, and was leased to Daphne du Maurier from 1943 to 1969.
Milton Hall, which Daphne du Maurier visited as a child, was built in 1594 and is the ancestral seat of the Fitzwilliam family. It is situated about three miles from Peterborough in what is now Cambridgeshire.
