The Anaconda Smelter Stack is the tallest surviving masonry structure in the world, with an overall height of about 585 feet (178.3 m), including a brick chimney 555 feet (169.2 m) tall and the downhill side of a concrete foundation 30 feet (9.1 m) tall. It is a brick smoke stack or chimney, built in 1918 as part of the Washoe Smelter of the Anaconda Copper Mining Company (ACM) at Anaconda, Montana, in the United States. A terra cotta coating covered the entire brick chimney when new, but by the time the smelter closed in 1981, most had eroded away except for the upper 40%, exposing most of its bricks and reinforcing rods. The inside diameter at the bottom of the brick chimney is 76 feet (23.2 m) while that at the top is about 60 feet (18.3 m). The stack and its viewing area are now the two-part Anaconda Smoke Stack State Park.

Grays Harbor is an estuarine bay located 45 miles (72 km) north of the mouth of the Columbia River, on the southwest Pacific coast of Washington state, in the United States. It is a ria, which formed at the end of the last ice age, when sea levels flooded the Chehalis River. The bay is 17 miles (27 km) long and 12 miles (19 km) wide. The Chehalis River flows into its eastern end, where the city of Aberdeen stands at that river's mouth, on its north bank, with the somewhat smaller city of Hoquiam immediately to its northwest, along the bayshore. Besides the Chehalis, many lesser rivers and streams flow into Grays Harbor, such as the Hoquiam River and Humptulips River. A pair of low peninsulas separate it from the Pacific Ocean, except for an opening about two miles (3 km) in width. The northern peninsula, which is largely covered by the community of Ocean Shores, ends in Point Brown. Facing that across the bay-mouth is Point Chehalis, at the end of the southern peninsula upon which stands the town of Westport.

The Krepost Sveaborg was an Imperial Russian system of land and coastal fortifications constructed around Helsinki during the First World War. The purpose of the fortress was to provide a secure naval base for the Russian Baltic fleet and to protect Helsinki and block routes to Saint Petersburg from a possible German invasion. Krepost Sveaborg was part of Peter the Great's Naval Fortress, a coastal fortification system protecting access to Saint Petersburg by sea. The central part of Krepost Sveaborg was the old fortress of Suomenlinna where the fortress headquarters were located. Due to technological advances in artillery the old fortress was no longer capable of providing a sufficient protection, and a new main defensive line was built well beyond the old fortress boundaries. New coastal artillery guns built on outlying islands protected Krepost Sveaborg from the sea, while fortified lines constructed around Helsinki were intended to stop any attacks on land. The primary coastal guns were 10 in (254 mm) model 1891 guns and 6 in (152 mm) model 1892 Canet guns. Older 11 in (279 mm) model 1877 guns were also used. In summer 1917 the fortress had two hundred coastal or anti-landing guns, of which 24 were 10-inch guns in six batteries, 16 were 6-inch Canet guns in four batteries and twelve were 11-inch guns in three batteries. The artillery used in land fortifications included older coastal guns, old fixed carriage guns and newer light field guns. In March 1917, Krepost Sveaborg had a total of 463 guns, although many of them were obsolescent. Krepost Sveaborg was still partly incomplete in 1917 when the February Revolution halted most of the construction work. Some further construction work was carried out during the remaining year, but all work halted during the October Revolution. Following the Finnish Declaration of Independence, parts of the land fortifications were used in the Finnish Civil War. The coastal fortifications were later taken over by Finland to protect Helsinki, while the land fortifications were mostly abandoned and disarmed.

Fort de Villey-le-Sec, also known as Fort Trévise, is a fortification of the 19th century, built as part of the Séré de Rivières system of fortifications in Villey-le-Sec, France, one of the defenses of Toul. It is a unique example for its time of a defensive enclosure around a village. Conceived after the defeat of the Franco-Prussian War of 1870-71, the fort was located away from the main combat zone of World War I and has remained almost intact. The fort's preservation association has been at work since 1961 to restore and interpret the site. It has been included in the Inventory of Historic Sites and has been designated as a preserved natural area.
Fort Andrews was created in 1897 as part of the Coast Defenses of Boston, Massachusetts. Construction began in 1898 and the fort was substantially complete by 1904. The fort was named after Major General George Leonard Andrews, an engineer and Civil War commander, who assisted in the construction of nearby Fort Warren in Boston Harbor. It occupies the entire northeast end of Peddocks Island in Boston Harbor, and was originally called the Peddocks Island Military Reservation. Once an active Coast Artillery post, it was manned by hundreds of soldiers and bristled with mortars and guns that controlled the southern approaches to Boston and Quincy Bay. The fort also served as a prisoner-of-war camp for Italian prisoners during World War II, who were employed as laborers following the Italian surrender to the Allies in 1943. Today, the fort is abandoned, and is managed by the Massachusetts Department of Conservation and Recreation, as part of the Boston Harbor Islands National Recreation Area.

The AN/FPS-24 Radar was a long range early warning radar used by the United States Air Force Air Defense Command. It used a two-frequency signal in order to avoid fluctuation loss, which causes signals on single-frequency radars to fade in and out as the target moves. Reducing this effect results in a much steadier signal.
