Fort Ticonderoga, formerly Fort Carillon, is a large 18th-century star fort built by the French at a narrows near the south end of Lake Champlain in northern New York in the United States. It was constructed by Canadian-born French military engineer Michel-Alain Chartier de Lotbinière, Marquis de Lotbinière between October 1755 and 1757 during the Seven Years' War, often referred to as the French and Indian War in the US. It was of strategic importance during the 18th-century colonial conflicts between Great Britain and France, and again played an important role during the American Revolutionary War.
