This elegant three-story mansion was completed in 1763 by a crew hired by Captain John Moffatt. Captain Moffatt was a merchant-trader in New England’s tall pine trees which were used for masts on English sailing ships. He also traded in molasses and rum from the West Indies, and in luxury goods for the prosperous residents of Portsmouth. The front of the house overlooks the family wharf on the year-round harbor of the Piscataqua River.
