Thorntree (Kingstree, South Carolina)

Thorntree, also known as the Witherspoon House, is a historic plantation house located at Kingstree, Williamsburg County, South Carolina. It was built in 1749 by immigrant James Witherspoon (1700-1765), and is a two-story, five-bay, frame "I-house" dwelling with a hall and parlor plan and exterior end chimneys. It features full-length piazzas on the front and rear elevations. To preserve it, the house was moved from an inaccessible rural site to Kingstree on land donated as a memorial park, known as Fluitt-Nelson Memorial Park. The house has been restored to its 18th-century appearance and is open to the public by appointment with the Williamsburg Historical Society.

It was listed in the National Register of Historic Places in 1970.
