Appomattox Iron Works is a historic iron foundry complex located at Petersburg, Virginia. The complex consists of nine buildings: the machine shop, the mill store, the supply room, the pipe shop, the carpenter's shop and pattern shop, the core room, the foundry building, the blacksmith's shop, and the ruins of a stable. The machine shop at 28 Old Street is the oldest structure in the complex. It was built between 1810 and 1825, and is a three-story, four-bay, Federal style brick building. The Appomattox Iron Works operated at this location from 1899 until 1972.[3]
