Orange Grove, also known as the Gaillard-Colclough House, is an historic 39.9acre plantation and its plantation house located at Gaillard's Crossroads, (intersection of Peach Orchard Road and Black River Road), north of Dalzell, South Carolina. It was added to the National Register of Historic Places on 19 August 1993.Built in 1851 in a South Carolina Lowcountry vernacular style of architecture, the house was seriously damaged by a tornado on 30 April 1924, and was rebuilt thereafter so that it now appears as a "raised cottage with a Prairie or Craftsman roof."The main axis of the plantation house runs NW-SE, with the façade on the SE face.
