About this map

Portsmouth sits at the heart of this coastal survey, where the Piscataqua River separates New Hampshire from Maine. The maritime character of the region is evident in the dense concentration of waterfront infrastructure, including the General Sullivan Bridge and the Maine-New Hampshire Bridge. The map details the transition from the urban core of Christian Shore and Atlantic Heights to the residential pockets of Pannaway Manor and the rural reaches of Greenland and Rye.

Genealogical interest is particularly high due to the preservation of numerous small burial sites such as the African Burying Ground, Cole Family Burial Ground, and the Christian Remick Memorial Site. Moving inland toward the southwest, the landscape opens into tidal marshes and creeks, including Great Bay and Winnicut Mills, reflecting the historical importance of water access for both industry and early settlement.
