The Oliver G. Traphagen House, also known as Redstone, is a historic residential building in Duluth, Minnesota, United States. Built in 1892 as a duplex, it was designed and inhabited by architect Oliver G. Traphagen (1854–1932).[2] The building was listed on the National Register of Historic Places in 1975 for its local significance in the theme of architecture.[3] It was nominated for its association with Traphagen, recognized together with his business partner Francis W. Fitzpatrick as Duluth's leading architects of the late 19th century.[2]
