Its buildings date from about 1812 to the 1930s, beginning with limestone structures of 1816-19.","why_significant":"The nomination argues that the post is remarkable for its uninterrupted historic and architectural continuity, with limestone 1816 buildings, brick 1890s quarters around the parade grounds, and 1920s structures all surviving. It was a strategic link in the defense of the northern U.S. boundary, and figures from Ulysses S. Grant to Fiorello LaGuardia were associated with it. It is also tied to the 1817 visit of President James Monroe.","narrative":"Madison Barracks is a military post of about 113 acres on Lake Ontario at Sackets Harbor, New York, used continuously from 1812 until World War II. Its buildings show three main construction periods. Limestone officers' quarters known as the Stone Row, a hospital, a bakery and warehouses date from 1816-19. Brick quarters, barracks, a guard house and a rusticated stone water tower followed in the 1890s, and brick and concrete block structures were added in the 1920s. Most buildings face two adjoining parade grounds. A stone arch bridge over Mill Creek, built around 1812, still carries traffic. The post was ordered built in 1815 by General Jacob Brown and named for James Madison. President James Monroe visited in 1817, and Ulysses S. Grant served there as a young lieutenant. It was listed because the grounds and buildings preserve a continuous record of the nation's northern frontier defense and of military architecture across more than a century.","period_of_significance":"19th Century (the form also notes a 130-150 year span of military use from 1812)","architect_builder":"William Smith credited with design of the 1816-19 limestone buildings; Major Samuel Brown supervised construction","architectural_style":"Richardsonian detailing on the Mess Hall and Barracks; colonial revival for the 1939 barracks; otherwise not formally classified","criteria":[],"status_note":"Condition is marked as mixed on the form.
