1916 Map of Casco Bay

USGS Topo · Published 1925

About this map

Fort Mc Kinley and a dense network of coastal defenses stand guard over the entrance to Portland Harbor in the years leading up to the first World War. This maritime landscape is defined by its complex shoreline, where the Atlantic Ocean meets an intricate archipelago of islands including Great Chebeague Island, Long Island, and Cushing Island. The map illustrates the region's reliance on waterborne transport, marking numerous ferry and steamboat lines such as the Boston and New York Steamboat Route and the Boothbay and Rockland Route. On the mainland, the industrial and residential growth of South Portland and Falmouth Foreside is supported by the Grand Trunk RR and the Portland and Yarmouth Electric RR. Local institutions like the Marine Hospital and Pine Grove School reflect the established social fabric of Cumberland County during this era.
