Winter Quarters State Historic Site, Plantation in the National Register of Historic Places in Tensas Parish, Louisiana, United States

Winter Quarters State Historic Site is a preserved antebellum cotton plantation south of Newellton, on Lake St. Joseph, an oxbow lake formed from an old bend of the Mississippi River. Its main house began in 1805 as a hunting lodge built by Job Routh and was soon enlarged into a residence.

Job Routh built the original hunting lodge in 1805; it was soon enlarged into a residence and later belonged to Haller Nutt's wife. Before the 1863 Vicksburg Campaign, fifteen plantations lined Lake St. Joseph, but Union troops destroyed all except Winter Quarters, where they were housed in 1863–1864. General Ulysses S. Grant spared it because Nutt was pro-Union.

The name Winter Quarters comes from when people only occupied the estate during colder months. The house shows how plantation owners and their families lived and spent their time in this rural region.

The grounds were heavily damaged by a tornado in 2011 and are currently not open to the public. The state has not announced a timeline for reopening yet.

Union troops used Winter Quarters as winter housing in 1863–1864, sparing it because the owner, Haller Nutt's wife, was pro-Union; Grant ordered the plantation protected. In the 1950s the Doyle family lived here, and daughter Barbara Sue Doyle Hage (1949–2016), the 1962 March of Dimes poster child, was at her death the oldest known survivor of spina bifida.
