It was severely damaged during the war, left in ruins, and although there was some rebuilding, the fort as conceived was never completed.

Portland Harbour is located beside the Isle of Portland, Dorset, on the south coast of England. Construction of the harbour began in 1849; when completed in 1872, its 520-hectare (1,300-acre) surface area made it the largest man-made harbour in the world, and remains one of the largest in the world today. It is naturally protected by Portland to the south, Chesil Beach to the west and mainland Dorset to the north. It consists of four breakwaters — two southern and two northern. These have a total length of 4.57 km and enclose approximately 1,000 hectares of water.

Together with Popton Fort on the opposite shore, it provided an interlocking field of fire, and represented the last layer of defence before reaching the Royal Naval dockyard at Pembroke Dock. Construction began in 1860 and was completed in 1863 at a cost of £55,000. It is a large battery, with eleven guns in casemates, eight in an open battery above, with another nine in an open flank battery, and a large barracks to the rear. It is a D-shaped structure, with a bomb-proof roof which protected the barracks and other buildings from mortar projectiles. On its landward side, it was protected by a deep ditch, and on the seaward side by a counter-scarp gallery. The associated casemate battery is located further down the headland and separated from the fort.

Fort Gilkicker is a historic Palmerston fort built at the eastern end of Stokes Bay, Gosport, Hampshire England to dominate the key anchorage of Spithead. It was erected between 1863 and 1871 as a semi-circular arc with 22 casemates, to be armed with five twelve-inch guns, seventeen ten-inch guns and five nine-inch guns. The actual installed armament rather differed from this. In 1902 the RML guns were replaced by two 9.2-inch and two six-inch BL guns, and before the First World War the walls were further strengthened with substantial earthwork embankments. The fort was disarmed in 1956 and used for storage until 1999, and is currently in a state of disrepair.
Fort Widley is one of the forts built on top of Portsdown Hill between 1860 and 1868 on the recommendation of the Royal Commission on the Defence of the United Kingdom. It was designed, along with the other Palmerston Forts atop Portsdown, to protect Portsmouth from attack from the rear.

Until disarmament in 1946, the areas protected by the fort were the entire Chesapeake Bay and Potomac River regions, including the water approaches to the cities of Washington, D.C. and Baltimore, Maryland, along with important shipyards and naval bases in the Hampton Roads area. Surrounded by a moat, the six-sided bastion fort is the largest fort by area ever built in the United States.

A fire control tower is a structure located near the coastline, used to detect and locate enemy vessels offshore, direct fire upon them from coastal batteries, or adjust the aim of guns by spotting shell splashes. Fire control towers came into general use in coastal defence systems in the late 19th century, as rapid development significantly increased the range of both naval guns and coastal artillery. This made fire control more complex. These towers were used in a number of countries' coastal defence systems through 1945, much later in a few cases such as Sweden. The Atlantic Wall in German-occupied Europe during World War II included fire control towers.
Fort DuPont, named in honor of Rear Admiral Samuel Francis Du Pont, is located between the original Delaware City and the modern Chesapeake and Delaware Canal on the original Reeden Point tract, which was granted to Henry Ward in 1675.

In 2016, the acreage which is not in the state park system was annexed into Delaware City.

Both forts were part of the Coast Defenses of Portland, renamed the Harbor Defenses of Portland in 1925, a command which protected Portland's port and naval anchorage 1895-1950. In 1946 Fort Lyon was closed and turned over to the City of Portland. After Fort McKinley's closure it was transferred to the United States Navy, which sold the site to private interests in 1961. The Fort McKinley Historic District was listed on the National Register of Historic Places in 1985.
