Shirley Heights is a military complex, overlooking English Harbour and named after Sir Thomas Shirley, Governor of the Leeward Islands, who built up Antigua’s defences in 1781. Britain had lost all her West Indian colonies (including North America) at this time except Antigua and Barbados. Much effort, therefore, was put into Antigua’s defences, mainly because of the island’s great sugar producing value and the important Nelson's Dockyard. The Lookout is the highest point in Shirley Heights (about 490 ft.) and affords a superb view of English and Falmouth Harbours, some say the best view in Antigua.
