Although not really representative of any true Jersey architectural style, Mainland, which stood at Bel Royal from the early 19th century until it was demolished in 1975, was nevertheless an example of the grand houses built by the 'Cod barons' in the 1800s.
This Georgian mansion was built on the profits of the cod trade by the Gibaut family of merchants, but later generations established a very successful farm producing the heaviest crops of apples from the orchards.
The house as it stood before demolition in 1975 appears to have been built for Philippe Gibaut (1764-1842), who was married to Elizabeth Gibaut, but some of the datestones at the property before its demolition are believed to have given misleading clues to its age. The main house was probably early 19th century, with a later wing added. Outbuildings may have been as early as mid-18th century.
