Callaway Plantation is a historic restoration project of the City of Washington. History is brought back to life for those who visit the three restored homes, structures, farm and fields. The great manor house was constructed in 1869. The mansion was the focal point of a 3,000 acre cotton plantation that stretched as far as the eye could see in all directions. The home remains virtually unaltered. Connected to the rear of the mansion by a breezeway is a self-contained brick kitchen. The oldest building in the complex, the hewn log cabin was constructed around 1785. It contains many early domestic and agricultural tools as well as primitive furniture. A smokehouse, pigeon house, barn and cemetery are among other structures to be found on the site. The Gilmer House, built in 1800 and located on lands adjacent to Callaway Plantation, is the boyhood home of George R. Gilmer who served as Georgia's governor from 1827 to 1831 and from 1837 to 1839.
