Fort George is situated on the Titchfield Peninsula in the town of Port Antonio, in the parish of Portland, Jamaica. The proposal for a fort in Port Antonio was first discussed in 1728, when a committee of the House of Assembly met to consider measures to be taken in the face of a possible Spanish invasion. In 1729, Christian Lilly was assigned the task of building a fort which, after being built, became known as Fort George in honour of King George I of Great Britain. Lilly had built the some of the walls at the Royal Citadel, Plymouth, and the bastion at Fort George was designed as a smaller version of the Citadel.
