Located just steps away from vibrant downtown Portsmouth, this historic federal home built in 1804 features 5,100+/- sq ft, 6 bedrooms and 6.5 bathrooms. Known as the Pickering-Heffenger house, these walls have a story to tell. It was host to a peace treaty ball between the Japanese and Russians during the Treaty of Portsmouth in 1905.

History meets today's standards seamlessly with a large bright updated kitchen featuring stainless appliances, loads of cabinetry and a large center island.
