Fort Ticonderoga, formerly Fort Carillon, is a large 18th-century fort built by the French at a narrows near the south end of Lake Champlain in upstate New York in the United States. It was constructed by Michel Chartier de Lotbinière, Marquis de Lotbinière between 1754 and 1757 during the Seven Years' War, often referred to as the French and Indian War in the USA. It was of strategic importance during the 18th-century colonial conflicts between Great Britain and France, and again played a role during the American Revolutionary War.
