The Harriet Barber House, home of Reverend Samuel Barber and his wife Harriet McPherson Barber, is significant for its association with the South Carolina Land Commission during the late nineteenth century. Samuel Barber purchased 42.5 acres of land in Richland County, part of the tract known as the Hopkins Turn Out Tract, at $5.00 per acre. The land on which the house stands has remained in the same family since May 24, 1872. It appears to be the only existing house in Lower Richland County built on land purchased through this program by former slaves. The property was officially entered in the National Register of Historic Places in April 1986. The Harriet Barber House Restoration Project received the first $25,000 grant from the Richland County Conservation Commission in 2006.
