Rankin-Harwell House, Greek Revival plantation house in Florence County, US.

The Rankin-Harwell House is a two-story frame dwelling built in 1857 in the Greek Revival style. Twenty-two freestanding Doric columns of stuccoed brick surround it on three sides. It stands on a raised basement and is covered by a low-pitched hipped roof.

The house was built in 1857 and placed on the National Register of Historic Places in 1974. This recognition honored its importance in South Carolina's architectural history.

The house carries several names: The Columns, Carolina Hall and the James Harwell House. The first two point to its most visible feature, the 22 Doric columns, and to a later use of the building. The property is listed on the National Register of Historic Places, and the columns remain the element visitors notice first.

The house stands near Florence, Florence County, South Carolina, off South Carolina Highway 305. The raised basement means the main floor is reached by steps, and the unpaved grounds can be soft after rain. The property is privately owned and not open as a public museum, so the columns are best seen from the road.

The house carries four names in the records: Rankin-Harwell House, The Columns, Carolina Hall and James Harwell House. Its 22 Doric columns are stuccoed brick rather than stone, and they wrap three sides of the frame, leaving the fourth side open.
