Bridgetown is the only city outside the present United States that George Washington visited. (George Washington House, the house where he stayed, is included within the boundaries of the Garrison Historic Area.) Two of Washington's ancestors, Jonathon and Gerrard Hawtaine, were early planters on the island.  Their grandmother was Mary Washington of Sulgrave, Northamptonshire, England. In 2011, historic buildings in Bridgetown were designated as a protected area by UNESCO.
