Old House Plantation, Historic plantation and archaeological site in Jasper County, United States.

Old House Plantation is a historic site in Jasper County with preserved structures and archaeological remains from the antebellum era. The grounds display building foundations and artifacts that show how farming and daily life were organized on this property.

The property was added to the National Register of Historic Places in 1997 and is connected to Thomas Heyward Jr., a signer of the Declaration of Independence. Its importance comes from documenting agricultural development and how life changed on plantations across different time periods.

The site is named for the main house of Daniel Heyward's plantation, and it holds the Heyward family cemetery enclosed by a brick wall, where Thomas Heyward Jr. is buried. Visitors can look for the two probable flanking outbuildings, one likely a kitchen, and the remains of a tidal mill and stable.

The site lies near Ridgeland in Jasper County, South Carolina, and is reached by road; the sources record no visitor facilities, guided tours or opening arrangements. The main house was destroyed by fire in 1865, so what remains is an archaeological site with foundations, outbuilding traces, a tidal mill, a stable and the Heyward family cemetery enclosed by a brick wall. Expect uneven ground and plan to walk the property to read the layout.

Excavations here have uncovered objects that show how different people lived and worked at the property across many years. The findings span multiple historical phases and reveal surprising details about everyday life that written records often overlook.
