Most of the town's 500 homes were built in the 1920s on land owned by the railroad. The 1920s-era commercial district consisted of four square blocks, of which about one dozen buildings remain as representatives of western frontier commercial architecture. Roslyn has many examples of Victorian elegance in its surviving buildings, as well as simple miner's shacks. The town of Roslyn was listed on the National Register of Historic Places in 1978. Recently, Roslyn became a Certified Local Government. Its Historic Preservation Commission restored the Roslyn Cafe, a local landmark.
