Portsmouth Historical Society, founded in 1917, is a nonprofit devoted to championing the history, arts, and culture of the Portsmouth region through acquisitions, preservation, museum exhibitions, programs, and publications. It operates two facilities: Discover Portsmouth and the 1758 John Paul Jones House Museum and Garden, a national historic landmark. We are dedicated to increasing public understanding and enthusiasm for local history. Our trustees, staff, sponsors, and members believe strongly that the uniqueness of Portsmouth is defined by the city’s past. Our long term vision is to protect and promote Portsmouth’s cultural heritage.
