[1] Located near the shore of the inlet of Watermouth, near Ilfracombe, Devon, the castle houses a collection of Victorian antiques centred on domestic tools and amusement machines, a family theme park and holiday apartments.

John Swete visited Watermouth, before the construction of the Georgian castle, as part of his travels in 1796, and was entertained by Mr Davie.

Watermouth Castle had been used as a military hospital during World War I, and in the 1920s she started to sell the Berrynarbor farms and cottages.

[6] The castle passed through the hands of many short-term owners and property speculators but was at last purchased by Keith Wickenden (1932–1983), a Conservative MP for Dorking South and businessman.

The castle was turned into an amusement centre, which was run by the Haines family (specifically Richard's sons Antonie and Jonathan) until 2023, when the owners of Hobbledown "The Escapade Group" took over the park.
