The Hoffman Round Barn, also known as Gentry Round Barn, is a historic round barn and national historic district located near Wolftown, Madison County, Virginia. The district encompasses two contributing buildings, one contributing site and one other contributing structure. The barn was built in 1913. It is a 1+1⁄2-story, wood frame barn with 12 sides and a 12-sided standing-seam metal, mansard-like roof. A wooden center silo protrudes several feet above the level of the main roof, has a gable-roofed dormer on the east side, and is capped by a metal roof, resembling a cupola. Associated with the barn are the contributing Hoffman farmhouse and family cemetery.[3]
