Polridmouth Cove is significant to Rebecca because it is the real-life location of the romantic beach cove that Rebecca de Winter lived in and died. Daphne du Maurier lived close to this remote cove in Cornwall, England and used it to create the setting for this gothic novel.

This location illustrates Gothic Convention because is it isolated, liminal, and mirrors the secrets and moral decay of her characters. Mapping this location proves all of those points, this location is very isolated and alone, really showing the readers how Maxim was able to get away and how Rebecca had to suffer all alone.
