Among the oldest surviving buildings on the island and one of the first erected on its south end, the Chatham Artillery Club was one of several private social clubs from the resort era that provided its members with hotel accommodations. Its typology is essentially the same as the Back River cottages, although the ground plan is different, with common rooms on the first story and bedrooms on the second story accessed by the exterior stairway on south side. Given its larger footprint, its pyramidal hipped roof rises taller than typical private cottages.
