Sagamore Hill Military Reservation

Sagamore Hill Military Reservation was built on state land in 1941-1942 by Battery C, 241st Coast Artillery Regiment of the Massachusetts National Guard, beginning shortly after the attack on Pearl Harbor in December 1941. Its mission was to protect the northern terminus of the Cape Cod Canal from possible naval attack; it was mirrored at the southern entrance by Butler Point Military Reservation. The site had two "Panama mounts" (circular concrete platforms) for two towed 155mm guns. It never fired its guns in defense but did play an important part in the defense of the canal. The reservation was deactivated on 1 April 1945.[1]
