Brim­stone Hill Fortress Nation­al Park is an out­stand­ing, well-pre­served exam­ple of 17th- and 18th-cen­­tu­ry mil­i­tary archi­tec­ture in a Caribbean con­text. Designed by the British and built by African slave labour, the fortress is tes­ti­mo­ny to Euro­pean colo­nial expan­sion, the African slave trade and the emer­gence of new soci­eties in the Caribbean.
