The Callaway Plantation is an open-air museum featuring several historic houses and other structures that is located in Washington, Georgia, U.S.A. The site was formerly a working plantation, owned by a family named Callaway since at least 1785. In its heyday, the plantation was 3,000 acres in size. The museum site is a 56-acre area containing the main houses that was donated by the family to the city of Washington in the 1980s. Additional buildings were moved to the site to represent typical plantation buildings. The museum is operated by the Washington-Wilkes Historical Foundation.
The main building is a brick mansion built by the Callaway family around 1860 out of Georgia red clay. It contains no indoor plumbing or electricity, since it was never modernized. Some of the original furniture is in the house.
The family's first home on the plantation was a log cabin built by Job Callaway in 1785. It burned down, but a cabin of similar design from the same era has been moved to the site. It consists of one room with a sleeping loft.
The family's second home still stands on the site, a two-story Federal Plain style house that they built around 1790.
