Madison Barracks

Madison Barracks was a military installation at Sackets Harbor that was built for occupation by 600 U.S. troops, a few years after the War of 1812. It was named for James Madison who had just completed his presidency in 1817. Construction began under the name Fort Pike. The facility is a National Historic Landmark and a historic district located at in Jefferson County, New York. The district includes 86 contributing buildings and two contributing structures. It includes the stone hospital, bakery, several warehouses known as "Stone Row," a stone water tower, and a series of brick buildings constructed in the 1890s as officers quarters, barracks, mess hall, and weapons storage and repair building.

Madison Barracks was the U.S. Army's primary post in upstate New York until Pine Camp (later renamed Fort Drum) was opened in 1908. Madison Barracks remained an active military installation through the end of World War II.

It is now operated as a residential community.

It was listed on the National Register of Historic Places in 1974.
