Historic Bridgetown and its Garrison, an outstanding example of British colonial architecture consisting of a well-preserved old town built in the 17th, 18th and 19th centuries, which testifies to the spread of Great Britain's Atlantic colonial empire. The property also includes a nearby military garrison which consists of numerous historic buildings. With its serpentine urban lay-out the property testifies to a different approach to colonial town-planning compared to the Spanish and Dutch colonial cities of the region which were built along a grid plan.
