Casco Bay islands and the burgeoning coastal suburbs of Falmouth and South Portland dominate this mid-century survey. The landscape is defined by its maritime defense and education history, featuring Fort McKinley on Great Diamond Island and the US Naval Reservation on Long Island. These installations, alongside Fort Preble and the US Naval Reserve Training Center near Spring Point, reflect the area's strategic importance during and after the World Wars.
