Portland and its surrounding harbor islands stand as a fortified maritime hub during the early twentieth century. This survey documents the extensive coastal defenses protecting Casco Bay, including Fort Williams, Fort Preble, and Fort McKinley. The city center is dense with industrial infrastructure, where the Grand Trunk Railway and Maine Central RR converge near Back Cove and the Fore River. Beyond the urban core, the landscape transitions into a network of small school districts and coastal hamlets. Genealogists can find numerous local institutions, from the Anderson School and Sawyer School to the prominent Evergreen Cemetery. Along the southern coastline, the burgeoning resort culture is evident at Old Orchard and Grand Beach, while the iconic Portland Head and Cape Elizabeth Light serve as vital navigational landmarks for the Atlantic Ocean trade routes.
