Brimstone Hill Fortress National Park

Brimstone Hill Fortress National Park is a UNESCO World Heritage Site, a well-preserved fortress on a hill on the island of St. Kitts, in the Federation of St. Christopher (St. Kitts) and Nevis in the Eastern Caribbean. It was designed by British military engineers, and was built and maintained by enslaved Africans. It is one of the best preserved historical fortifications in the Americas. The complex of fortifications were constructed on Brimstone Hill, a very steeply sloping hill situated close to the sea on the Western, Caribbean coast of St. Kitts.
