About this map

Casco Bay defines the character of this coastal area, where the harbor of Falmouth and the eastern edge of South Portland meet the Atlantic. The maritime landscape is dense with historical navigation and defense landmarks, including the iconic Portland Observatory and several island fortifications like Fort Gorges and Fort Scammel. This survey illustrates the intricate relationship between the mainland and the scattered islands, from Great Diamond Island to Cushing Island, each served by landings and marinas.

Industrial and community roots are visible through features like the Maine State Pier, Custom House Wharf, and the Marine Shipyard in the south. Genealogists and historians can trace older settlement patterns through the Eastern Cemetery and Old Settlers Cemetery, while landmarks such as Spring Point Ledge Lighthouse and Portland Breakwater Light highlight the era's reliance on lighthouse navigation for the busy Maine coast.
