Graniteville Historic District, Textile industrial district in South Carolina, US

Graniteville Historic District is a textile company town built by William Gregg near Aiken, South Carolina, between 1845 and 1849. It includes a mile-long power canal drawing from Horse Creek and Bridge Creek, the 1849 mill building, the 1847 Graniteville Academy, St. John's Methodist Church, and 26 surviving Carpenter Gothic worker houses on Gregg Street.

William Gregg founded this textile complex between 1845 and 1849 as one of the first factory towns in the Southern United States. The place pioneered combining industrial production with organized community living.

Gregg set aside lots inside the development for churches, and two were eventually built; St. John's Methodist Church, still standing, is the one that survives. Of the 100 Carpenter Gothic wooden worker houses Gregg put up in the 1840s, 26 remain in good condition, lining Gregg Street.

The historic district lies west of Aiken, on the east side of Horse Creek. The 1846 power canal runs north from the centre of Graniteville along the west side of Canal Street (South Carolina Highway 191), with the 1849 mill building and the surviving 1840s worker houses on Gregg Street nearby. The canal is no longer used for power.

The original power canal system from the 1840s stretches over a mile and still runs through the grounds today. This old engineering feat is often overlooked but shows the technical skill that went into the factory design.
