In 1666, a wooden fortification was constructed by French colonists on a promontory overlooking Grenada's natural harbour and named ''Fort Royale''. In 1705, work started on a new star fort on the same site, with four stone-built bastions, to the design of Jean de Giou de Caylus, the Chief Engineer of the "Islands of America" the French West Indies. It was completed in 1710.
