Beneventum Plantation House, Georgian plantation house in Georgetown County, United States.

Beneventum Plantation House is a two-story residence in Georgetown County featuring a one-story covered porch across the middle of its front with five evenly-spaced windows. The main structure shows Georgian design principles, with additions built at the rear section at a later date.

Beneventum Plantation House was built about 1750 as Prospect Hill Plantation, a two-story, five-bay Georgian house near Georgetown. The rear half was added about 1800, with further rear additions probably in the early 20th century. It was the home of Christopher Gadsden, Revolutionary War statesman and soldier, originator of the "Don't Tread on Me" flag and a Federalist Party leader. It was listed on the National Register of Historic Places in 1988.

Christopher Gadsden, who designed the historic 'Don't Tread on Me' flag and served as brigadier general in the Continental Army, resided at this estate.

The house remains in private ownership and cannot be entered by visitors, but a state historical marker is visible from the public road along Beneventum Road. You can view the exterior from the public right of way and read information on the roadside marker.

The house appears in the Historic American Buildings Survey as survey number SC-480, and photographs from that survey are held on Wikimedia Commons. The property was listed on the National Register of Historic Places in 1988, which is what protects the Georgian structure and its later rear additions today.
