The Marine Corps Poster Series highlights historic properties in Marine Corps care. The ACHP worked with staff at the Marine Corps and the National Park Service to support showcasing historic properties and giving the story of their founding and use by the Marines throughout history. The “Defending Our Cultural Heritage” sites featured included the Oldest Post in the Corps: Marine Corps Barracks Washington; World War II Legacy at Kaneohe Bay, Hawaii; Montford Point training camp for the first African American Marines at Camp Lejeune, North Carolina; 450-year Expeditionary Legacy at Parris Island, South Carolina; and Remembering California’s Ranches, San Diego, California, near Camp Pendleton.
