Because of its unusually high quality of preservation, nearly all of the community was placed on the National Register of Historic Places in 1977 as the "Wellsville Historic District".[3] Among the district's 48 contributing properties are an 1850s Methodist church, a small group of nineteenth-century commercial buildings, and the Wellsville House, an 1870s structure that has been used as a factory, museum, and restaurant.[4]: 9, 10
