Dammon Round Barn is a round barn just southeast of Red Wing, Minnesota, United States, adjacent to U.S. Route 61. The barn is listed on the National Register of Historic Places. It was built in 1914, with a foundation of Mississippi River limestone, and is 60 feet (18 m) in diameter and 60 feet (18 m) high. It was built during a time of agricultural growth in Goodhue County, when dairy cow herds were averaging 25 cows per farm and farmers were starting to build specialized barns. The round barn design was built around a silo and provided insulation for the silage, as well as making feeding and cleaning easier. Despite the efficiency, however, round barns were difficult to construct, and they were not widely adopted. Later in its history the barn was used for honey production of the bee keeping owners of the farm. In 2000 the Farm was purchased by Robin and Elaine Kleffman and the Dammon Barn underwent some significant restoration. A straightening of the walls and replacement of the original pillars for the upper floor support and a leveling and new installation of a floor in the top level of the barn makes this one of the most premiere remaining round barns in Minnesota.
