Brimstone Hill Fortress National Park, a UNESCO World Heritage Site, is the largest fortress ever built in the Western Caribbean. The island of Saint Kitts is home to the Warner Park Cricket Stadium, which was used to host 2007 Cricket World Cup matches. This made Saint Kitts and Nevis the smallest nation to ever host a World Cup event. Saint Kitts is also home to several institutions of higher education, including Ross University School of Veterinary Medicine, Windsor University School of Medicine, and the University of Medicine and Health Sciences.
