Fort Marion NM 100th Anniversary Pin

Fort Marion National Monument, now Castillo De San Marcos National Monument, is celebrating its 100th anniversary as a National Monument in 2024! The oldest masonry fort in the continental United States, this site dates back to 1672 when Spanish engineer Ignacio Daza began construction of it. Many sieges, changing of hands, and later becoming a U.S. Army base makes this place amazing to explore. Commemorate your trip and the 100th anniversary with the Fort Marion NM Pin.
