Sackets Harbor, New York

Sackets Harbor (earlier spelled Sacketts Harbor) is a village in Jefferson County, New York, United States. The population was 1,450 at the 2010 census. The village was named after land developer and owner Augustus Sackett, who founded it in the early 19th century.

The Village of Sackets Harbor is within the western part of the Town of Hounsfield and is west of Watertown. The heart of the village, with a Main Street and well-preserved 19th century buildings, has been recognized as the Sackets Harbor Village Historic District and listed on the National Register of Historic Places in 1983.

To support the War of 1812, the US Navy built a major shipyard and its headquarters for the Great Lakes at the village. Within a short period, more than 3,000 men worked at the shipyard. The Army constructed earthworks, forts, barracks and supporting infrastructure to defend the village and navy shipyard, and its troops also camped in the village. The thousands of military personnel made it seem like a city. By the fall of 1814, this was the third-largest population center in the entire state, after Albany and New York City. With its strategic protected harbor on Lake Ontario and military installations, the village had national importance through the 19th century.
