Citadel Hill is a hill that is a National Historic Site in Halifax, Nova Scotia, Canada. Four fortifications have been constructed on Citadel Hill since the city was founded by the English in 1749, and were referred to as Fort George—but only the third fort was officially named Fort George. According to General Orders of October 20, 1798, it was named after King George III. The first two and the fourth and current fort, were officially called the Halifax Citadel. The last is a concrete star fort.
Point Pleasant Park is a large, mainly forested municipal park at the southern tip of the Halifax peninsula. It once hosted several artillery batteries, and still contains the Prince of Wales Tower - the oldest Martello tower in North America (1796). The park is a popular recreational spot for Haligonians, as it hosts forest walks and affords views across the harbour and out toward the Atlantic.
The Western Heights of Dover are one of the most impressive fortifications in Britain. They comprise a series of forts, strong points and ditches, designed to protect the country from invasion. They were created in the 18th and 19th centuries to augment the existing defences and protect the key port of Dover from both seaward and landward attack; by the start of the 20th century Dover Western Heights was collectively reputed to be the 'strongest and most elaborate' fortification in the country. The Army finally withdrew from the Heights in 1956–61; they are now a local nature reserve.
Several boards have been appointed by US presidents or Congress to evaluate the US defensive fortifications, primarily coastal defenses near strategically important harbors on the US shores, its territories, and its protectorates.

The Hobart coastal defences are a network of now defunct coastal batteries, some of which are inter-linked with tunnels, that were designed and built by British colonial authorities in the nineteenth century to protect the city of Hobart, Tasmania, from attack by enemy warships. During the nineteenth century, the port of Hobart Town was a vital re-supply stop for international shipping and trade, and therefore a major freight hub for the British Empire. As such, it was considered vital that the colony be protected. In all, between 1804 and 1942 there were 12 permanent defensive positions constructed in the Hobart region.

Fort Nepean is a former defensive facility occupying part of Point Nepean, Victoria, Australia. It was part of a network of fortifications, commanded from Fort Queenscliff, protecting the narrow entrance to Port Phillip. It is now part of Point Nepean National Park and a local tourist attraction.
The RML 9-inch guns Mark I – Mark VI were large rifled muzzle-loading guns of the 1860s used as primary armament on smaller British ironclad battleships and secondary armament on larger battleships, and also ashore for coast defence. It should not be confused with the RML 9-inch Armstrong Gun, used by the Dutch navy, the Spanish Navy, and other navies.
Coastal defenceand coastal fortification are measures taken to provide protection against military attack at or near a coastline, for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed. Coastal artillery fortifications generally followed the development of land fortifications, usually incorporating land defences; sometimes separate land defence forts were built to protect coastal forts. Through the middle 19th century, coastal forts could be bastion forts, star forts, polygonal forts, or sea forts, the first three types often with detached gun batteries called "water batteries". Coastal defence weapons throughout history were heavy naval guns or weapons based on them, often supplemented by lighter weapons. In the late 19th century separate batteries of coastal artillery replaced forts in some countries; in some areas these became widely separated geographically through the mid-20th century as weapon ranges increased. The amount of landward defence provided began to vary by country from the late 19th century; by 1900 new US forts almost totally neglected these defences. Booms were also usually part of a protected harbor's defences. In the middle 19th century underwater minefields and later controlled mines were often used, or stored in peacetime to be available in wartime. With the rise of the submarine threat at the beginning of the 20th century, anti-submarine nets were used extensively, usually added to boom defences, with major warships often being equipped with them through early World War I. In World War I railway artillery emerged and soon became part of coastal artillery in some countries; with railway artillery in coast defence some type of revolving mount had to be provided to allow tracking of fast-moving targets.

Breakneck Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Ministry of Defence property at the Upper Rock Nature Reserve, north of Lord Airey's Battery. It is one of a dozen batteries in Gibraltar that had 9.2-inch (233.7 mm) guns installed around the turn of the twentieth century. The emplacement features a 9.2-inch Mark X breech-loading gun on a Mark V mounting. The battery was refurbished by 10 Signal Regiment in 2012 and 2016 whilst being on Ceremonial duties whilst the Gibraltar Regiment where on exercise and is one of three surviving 9.2-inch gun emplacements at the Upper Ridge of the Rock of Gibraltar. By the late twentieth century, the 9.2-inch guns in Gibraltar, Bermuda, Portugal, South Africa, and Australia were the remaining examples of an emplacement that at one point had been mounted at strategic locations across the British Empire.
Devils Battery or Devils Point Battery, Hartlen Point or Hartlen Point Tunnels, was a complex military installation at the mouth of Halifax Harbour in the community of Eastern Passage at Hartlen Point, Canada. It was built between 1940 and 1945 to protect the Halifax area against the German navy. It was operational until the 1950s. The site had three 9.2 inch (234 mm) breech-loading Mark X guns, operated by the 53rd Heavy Battery of the 1st (Halifax) Coast Regiment. It is now a golf course; the original underground armaments remain buried. Devils Battery was named for Devils Island which is adjacent to the embankment of Hartlen's Point.
