About this map

Portland and South Portland dominate the coastline in this detailed survey of the southern Maine shore, where the Grand Trunk Railway meets the Fore River. The landscape is heavily marked by maritime defense and public institutions, from the Fort McKinley Naval Res on Great Diamond Island to the U S Marine Hospital and the Maine School for the Deaf on Mackworth Island. These landmarks illustrate the region's strategic importance and its role as a hub for state services during the mid-twentieth century.

Beyond the urban centers, the map traces the intricate archipelago of Casco Bay, featuring large landmasses like Great Chebeague Island and Cousins Island. Coastal developments such as Falmouth Foreside and Mountainview Park show the post-war suburban shift toward the water. Historic navigational aids, including the Portland Head Lighthouse and Cape Elizabeth Lighthouse, stand as permanent fixtures along the jagged points of Cape Elizabeth and Two Lights State Park.
