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.
A blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force and cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt.
Fort McClary is a former defensive fortification of the United States military located along the southern coast at Kittery Point, Maine at the mouth of the Piscataqua River. It was used throughout the 19th century to protect approaches to the harbor of Portsmouth, New Hampshire and the Portsmouth Naval Shipyard in Kittery. The property and its surviving structures are now owned and operated by the State of Maine as Fort McClary State Historic Site, including a blockhouse dating from 1844.
Fort Hamilton is a United States Army installation in the southwestern corner of the New York City borough of Brooklyn, surrounded by the communities of Bay Ridge and Dyker Heights. It is one of several posts that are part of the region which is headquartered by the Military District of Washington. Its mission is to provide the New York metropolitan area with military installation support for the Army National Guard and the United States Army Reserve. The original fort was completed in 1831, with major additions made in the 1870s and 1900s. However, all defenses except about half of the original fort have been demolished or buried.
Fort Wadsworth is a former United States military installation on Staten Island in New York City, situated on The Narrows which divide New York Bay into Upper and Lower halves, a natural point for defense of the Upper Bay and Manhattan beyond.

It comprises several fortifications, including Fort Tompkins and Battery Weed and was given its present name in 1865 to honor Brigadier General James Wadsworth, who had been killed in the Battle of the Wilderness during the Civil War. Fort Wadsworth is now part of the Staten Island Unit of Gateway National Recreation Area, maintained by the National Park Service.

When built, it was named Fort Richmond, as was a previous fort on the site.

Nutter's Battery is a scenic overlook in the North Woods of Central Park in Manhattan, New York City, overlooking the Harlem Meer to the north. The battery was built during the War of 1812 as a small part of an extensive system of fortification intended to defend against a British invasion from the north. After the war, the wall fell into ruin and eventually disappeared. The Parks Department built a low wall in 1945 to mark the spot, and the Central Park Conservancy rebuilt the wall in 2014, adding paths and planting. The battery was named after Valentine Nutter, who owned the surrounding property.

Fort Clinton was a stone-and-earthworks fortification on an elevation within what is now Central Park in New York City. It was built in 1814 near the present line of 107th Street, slightly west of Fifth Avenue. According to maps of the time, Fort Clinton was the easternmost of a connected series of forts, connected to Nutter's Battery on the west by earthworks and a gatehouse over the Old Post Road at the bottom of McGowan's Pass. Fort Clinton and Nutter's Battery were commanded from a third fort at the top of the pass, Fort Fish, which had a sweeping view of Long Island Sound, northern Manhattan, and Westchester County. Fort Fish was across the road from Fort Clinton and connected to Nutter's Battery by another line of earthworks.

The first Lieutenant Governor of Upper Canada, John Graves Simcoe, planned defences for the mouth of Toronto Harbour at Fort York, along with the Gibraltar Point Blockhouse that was situated south of the harbour's entrance.
The fortifications of Plymouth in Devon are extensive due to its natural harbour, its commanding position on the Western Approaches and its role as the United Kingdom's largest naval base. The first medieval defences were built to defend Sutton Harbour on the eastern side of Plymouth Sound at the mouth of the River Plym, but by the 18th century, naval activity had begun to shift westward to Devonport at the mouth of the River Tamar. During the Victorian era, advances in military technology led to a huge programme of fortification encompassing the whole of Plymouth Sound together with the overland approaches. Many of these works remained in military use well into the 20th century.
The Harbor Defenses of New York was a United States Army Coast Artillery Corps harbor defense command. It coordinated the coast defenses of New York City from 1895 to 1950, beginning with the Endicott program, some of which were located in New Jersey. These included both coast artillery forts and underwater minefields. The command originated c. 1895 as an Artillery District(s) and became the Coast Defenses of Eastern New York and Coast Defenses of Southern New York in 1913. Circa 1915 the Coast Defenses of Sandy Hook separated from the latter command. In 1925 the commands were renamed as Harbor Defense Commands, and in 1935 the Harbor Defenses of Eastern New York was almost entirely disarmed, although possibly retaining the minefield capability. The New York and Sandy Hook commands and the Harbor Defenses of Long Island Sound were unified as the Harbor Defenses of New York on 9 May 1942.
