The Granby Mill Village is quite possibly the best collection of mill housing remaining in the state today. Its compact and visually striking appearances making it a fine example of late nineteenth century mill village design and its association with the prominent W.B. Smith Whaley lends great historical importance to its level of significance. The predominant "saltbox" style houses were built 1897-1899. The neighborhood was listed in the National Register of Historic Places in 1993 and was designated a local Architectural Conservation District in 2010.
