My travelling instructions directed me to go to Carlisle, and then to diverge by a branch railway which ran in the direction of the coast..... When I rose the next morning and drew up my blind, the sea opened before me joyously under the broad August sunlight, and the distant coast of Scotland fringed the horizon with its lines of melting blue.
This puts Limmeridge House on the west coast of Cumbria, with a view of the Dumfries and Galloway area of Scotland to the north.
It has been suggested that Collins may have had Ewanrigg Hall, on the outskirts of Maryport, in mind when creating Limmeridge House.
Ewanrigg Hall was the home of the Christian family. Fletcher Christian, of Mutiny on the Bounty fame, was born there in 1764. The house was demolished in 1903.
Cumberland is an historic county of North West England. It is now incorporated into Cumbria, along with Westmorland and parts of historic northern Lancashire.
Wilkie Collins and Charles Dickens visited Cumberland on a walking tour in 1857. Towns they stopped at included: Hesketh Newmarket, where they stayed at the Queen's Head; Wigton, where Collins saw a doctor about a sprained ankle; and Allonby, where they stopped for two nights at The Ship -- described by Dickens as 'a capital little homely inn looking out upon the sea ... a clean nice place in a rough wild country'.
