1916 Map of Casco Bay

About this map

Coastal fortifications and maritime infrastructure dominate this mid-1910s survey of the Maine shoreline. The heavy military presence protecting Portland Harbor is visible through Fort McKinley, Fort Gorges, and Fort Williams, while the Quarantine Station on House Island and the Marine Hospital near Mackworth Island highlight the era's public health and harbor management. Inland, the Portland and Yarmouth Electric RR and the Grand Trunk RR show the region's reliance on both rail and trolley systems to connect coastal communities like Falmouth Foreside and South Portland. Numerous ferry routes and landings, such as Trefethen Landing and Mariner, define the social and economic movement across the islands of Casco Bay, while local landmarks like Meetinghouse Hill and Underwood Spring provide specific points of interest for genealogists tracing early twentieth-century neighborhood development.
