Ironworks in the context of Adolph Menzel

Ostrava (Czech pronunciation: [ˈostrava] ; Polish: Ostrawa; Silesian: Ôstrawa; German: Ostrau) is a city in the north-east of the Czech Republic and the capital of the Moravian-Silesian Region. It has about 283,000 inhabitants. It lies 15 km (9 mi) from the border with Poland, at the confluences of four rivers: Oder, Opava, Ostravice and Lučina. Ostrava is the third largest city in the Czech Republic in terms of both population and area, the second largest city in the region of Moravia, and the largest city in the historical land of Czech Silesia. It straddles the border of the two historic provinces of Moravia and Silesia. The wider conurbation – which also includes the towns of Bohumín, Havířov, Karviná, Orlová, Petřvald and Rychvald – is home to about 500,000 people, making it the largest urban area in the Czech Republic apart from the capital Prague.

Ostrava grew in importance due to its position at the heart of a major coalfield, becoming an important industrial engine of the Austrian empire. During the 20th century it was known as the "steel heart" of Czechoslovakia thanks to its status as a coal-mining and metallurgical centre, but since the Velvet Revolution (the fall of communism in 1989) it has undergone radical and far-reaching changes to its economic base. Industries have been thoroughly restructured, and the last coal was mined in the city in 1994. However, remnants of the city's industrial past are visible in the Lower Vítkovice area, a former coal-mining, coke production and ironworks complex in the city centre which retains its historic industrial architecture. Lower Vítkovice has applied for inclusion in the UNESCO World Heritage List.

Jesenice (Slovene: [jɛsɛˈnìːtsɛ] , German: Aßling) is the tenth-largest town in Slovenia, located in the traditional province of Upper Carniola. It is the seat of the Municipality of Jesenice spanning the southern side of the Karawanks, along Slovenia's border with Austria to the north. Renowned as a mining town, its ironworks and metallurgy industries being the driving force of the town's historical development.

Borrowstounness, commonly known as Bo'ness (/boʊˈnɛs/ boh-NESS), is a town and former burgh and seaport on the south bank of the Firth of Forth in the Central Lowlands of Scotland. Historically part of the county of West Lothian, it now lies within the Falkirk council area, 17 miles (27 kilometres) northwest of Edinburgh and 6+3⁄4 miles (11 kilometres) east of Falkirk. At the 2011 census, the population of Bo'ness was 15,100.

Until the 20th century, Bo'ness was the site of various industrial activities, including coal mining, saltmaking and pottery production. With its location beside the Forth, the town and its harbour grew in importance in the Industrial Revolution and later continued to grow into the Victorian era. Since the late 20th century, deindustrialisation has changed the nature of the town, with the coal mine closing in 1982 and the waterfront area now being primarily used for leisure purposes. However, some industry remains in the town including an ironworks and a timberyard/sawmill beside the Forth. The centre of the town contains several listed buildings and is part of a conservation area. The town is the home of the Museum of Scottish Railways and also a regional motor museum.

A carronade is a short, smoothbore, cast-iron cannon which was used by the Royal Navy. It was first produced by the Carron Company, an ironworks in Falkirk, Scotland, and was used from the last quarter of the 18th century to the mid-19th century. Its main function was to serve as a powerful, short-range, anti-ship and anti-crew weapon. The technology behind the carronade was greater dimensional precision, with the shot fitting more closely in the barrel, thus transmitting more of the propellant charge's energy to the projectile, allowing a lighter gun using less gunpowder to be effective.

Carronades were initially found to be very successful, but they eventually disappeared as naval artillery advanced, with the introduction of rifling and consequent change in the shape of the projectile, exploding shells replacing solid shot, and naval engagements being fought at longer ranges.

Penydarren Ironworks was the fourth of the great ironworks established at Merthyr Tydfil in South Wales.

Built in 1784 by the brothers Samuel Homfray, Jeremiah Homfray, and Thomas Homfray, all sons of Francis Homfray of Stourbridge. Their father, Francis, for a time managed a nail warehouse there for Ambrose Crowley. Most of the family were involved in trade as ironmasters or ironmongers (in this context meaning a manufacturer of iron goods). Samuel built Penydarren House on the opposite bank of the River Taf, as a home for the family locally.
