The Buchanan North and West Neighborhoods National Register Historic District wraps downtown on its north and west sides, and includes over 700 homes, barns, garages, sacred and commercial properties, and more. Its buildings represent over twenty-three architectural styles, and many were homes to city leaders, merchants, and employees of the former Clark Equipment and Electro-Voice companies. It was listed on the National Register of Historic Places in 2011.
