The Strathglass Park District, located in Rumford, Maine, encompasses one of the nation's finest early 20th-century mill worker housing complexes. Funded by Hugh J. Chisholm, owner of Rumford's paper mill, and designed by Cass Gilbert, the district encompasses a collection of 50 high quality brick duplexes, of similar yet varied construction, which were built in 1901-2 on a series of tree-lined streets, with a small park at the center. As of the district's listing on the National Register of Historic Places in 1974, only one of the Gilbert-designed houses had been destroyed. The company divested itself of the houses in the late 1940s, with most being sold to their occupants.
