Some history according to wikipedia
in the years before the entry of the U.S. into World War II, the belief that America's shore defenses were inadequate resulted in the 1940 Modernization of the Coastal Defense program.[3] Battery 223 was part of the effort to address the advances of offensive and defensive technology in the 1930s. Standardized and mass-produced fortifications were built on both the east and west coasts.[4]
Battery 223 was one of three 200-series fortifications built for Fort Miles, headquartered in Cape Henlopen, Delaware. Designed to host a 6-inch battery and survive a direct hit from battleships and aircraft, the structure was built with six-foot thick reinforced concrete walls and a thick blast proof roof; the entire building was covered with earth. The 6-inch guns had a nine-mile range.[4]
In addition to the three 200-series batteries, Fort Miles also had a 16-inch and a 12-inch battery, both located at Cape Henlopen. The 16-inch guns had a range of 26 miles. In all, assets of Fort Miles extended along 200 miles of shoreline, including a network of 20 fire control towers.[4]

As the war turned in favor of the Allies, lessening the need for coastal defense, and continuing advances in warfare technology rendered fixed coastal defenses obsolete, the Modernization of the Coastal Defense program was never completed. Battery 223 was decommissioned in 1944; all Army seacoast defense guns had been scrapped by 1948. By 1950, the Army had dismantled all of the fixed gun harbor defenses; the buildings were used for other military purposes or were declared surplus.[4]
Battery 223 was used for radio communications by the Navy at some point after 1958, a concrete pad was poured on the top the building to support a Quonset hut. Battery 223 became part of the Cape May Point State Park in 1962. Today the battery is no longer covered and is in...
