During colonial times and the American Revolutionary War, its strategic location often made Crown Point an important location. Situated on the west shore of Lake Champlain about 15 miles north of Fort Ticonderoga it provided a fortified position about a day's travel north of that site.
After the failure of the American Invasion of Canada in 1776, it represented the northernmost point of American control. During the British Saratoga Campaign in 1777, General Burgoyne organized a supply magazine here to support his attack of Ticonderoga.
The Town of Crown Point is an original town of the county, established in 1786 before Essex County was created. Parts of Crown Point were used to form the Towns of Elizabethtown (1798) and Willsboro (1788).
The modern settlement of the town began around 1800 with an influx of settlers from Vermont.
Crown Point holds the New York state January record low of -48.
