1893 Map of Casco Bay

About this map

Coastal defenses and navigational beacons dominate this late nineteenth-century survey of the Maine coastline. The strategic importance of the harbor is evident through the placement of Fort Georges, Fort Preble, and Fort Scammel, which guarded the approaches to Portland. Significant maritime landmarks, including the Portland Head Light and the dual Cape Elizabeth Lights, provided essential guidance for vessels navigating Lucks Sound and Casco Bay.
