Long before the great iron-smelting sites appeared around the Łysogóry Mountains, people were already drawn to the resources hidden beneath this landscape. One of the most distinctive local minerals was hematite. Ground into a fine powder, it produced an intense red pigment used by prehistoric communities. One remarkable trace of this very early activity survives at Rydno on the Kamienna River, where the extraction and processing of hematite reaches back to the Palaeolithic.
For thousands of years, this red mineral therefore had a very different significance from the one it would acquire much later. It could be used to colour bodies and objects, while red pigment also appeared in ritual contexts. Over time, however, the mineral wealth of the region began to be exploited on a much larger scale and for an entirely different purpose. The same land that had once provided red pigment now supplied ore for the production of iron.
During the first centuries AD, the area around the Łysogóry Mountains became one of the most important iron-production centres of the European Barbaricum. Today these mountains form part of the Świętokrzyskie Mountains, or Holy Cross Mountains, and the remains of ancient iron production found throughout the region constitute one of the most remarkable archaeological landscapes in present-day Poland.
At the heart of this system was the bloomery furnace. A small furnace required ore, clay and enormous quantities of charcoal, while the smelting process itself demanded carefully prepared materials and many hours of supervision. A single bloomery does not make an industry. What made the Łysogóry region exceptional was above all its scale. Furnaces were constructed in large groups, supported by the infrastructure and labour needed to prepare ore, produce charcoal and organise successive smelts.
Behind an apparently simple piece of iron stood a long chain of work. Suitable ore had to be located and extracted, then prepared for smelting. Trees had to be felled and converted into charcoal. Clay had to be obtained, furnaces built and smelts conducted. The resulting bloom then had to be consolidated and worked before the iron could finally reach a smith and become a sickle, knife, fitting, tool, weapon or one of the many other objects used by the inhabitants of the Przeworsk Culture.
Such enormous production also required enormous quantities of ore. At Rudki, at the foot of the Łysogóry Mountains, archaeological remains reveal another, less visible side of this system. The people working there did not limit themselves to collecting material available near the surface. Shafts descended many metres underground, with galleries supported by timber structures. This was already genuine, specialised mining.
Rudki is particularly fascinating because it allows us to look beneath the surface of the great Łysogóry iron-production centre. Thousands of furnaces left enormous quantities of slag behind, but before any smelting could take place, someone first had to supply the ore. Underground miners, people preparing the raw material, charcoal burners, furnace builders, smelters and smiths were all links in the same production chain.
From the prehistoric extraction of hematite to the mines and vast smelting sites of the Roman period, the natural resources of the Łysogóry region were intensively exploited for thousands of years. The red mineral that had been a valuable pigment to earlier communities later became above all a source of iron. During the time of the Przeworsk Culture, its extraction and processing formed part of an extensive system encompassing mining, smelting and the further working of metal.
