The Völklingen Ironworks in western Germany close to the border with France cover 6 ha and are a unique monument to pig-iron production in Western Europe. No other historic blast-furnace complex has survived that demonstrates the entire process of pig-iron production in the same way, with the same degree of authenticity and completeness, and is underlined by such a series of technological milestones in innovative engineering. The Völklingen monument illustrates the industrial history of the 19th century in general and also the transnational Saar-Lorraine-Luxembourg industrial region in the heart of Europe in particular. The Ironworks are a synonym for and a symbol of human achievement during the First and Second Industrial Revolutions in the 19th and beginning of the 20th centuries.
The iron-making complex dominates the townscape of Völklingen. It contains installations covering every stage in the pig-iron production process, from raw materials handling and processing equipment for coal and iron ore to blast-furnace iron production, with all the ancillary equipment, such as gas purification and blowing equipment.
The installations are exactly as they were when production ceased in 1986. The overall appearance is that of an ironworks from the 1930s, since no new installations were added after the rebuilding of the coking plant in 1935. There is considerable evidence of the history of the works in the form of individual items that have preserved substantial elements of their original form. Large sections of the frames and platforms of the blast furnaces, for example, have not been altered since their installation at the turn of the 19th to 20th centuries. Much of the original coking plant survives, despite the 1935 reconstruction, notably the coal tower of 1898. Six of the gas-blowing engines, built between 1905 and 1914, are preserved, as are the suspended conveyer system of 1911 and the dry gas purification plant of the same time. In addition, remains of Buch´s puddle ironworks of 1873 are preserved in the power station below the blast furnaces.
Völklingen Ironworks was declared by UNESCO as a World Heritage site in 1994.References:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
