The Krzemionki Prehistoric Striped Flint Mining Region has been included in the List this year. ICOMOS in its evaluation had asked for a Referral, mostly because of the need for adequate protection of all its components and the implementation of the management plan. Outstanding Universal Value has been proven though, also compared to the already inscribed Flint Mines of Spiennes. So an inscription was no surprise. On my recent Pentecost trip to Eastern Poland I made a small detour between Warsaw and Zamosc to check out what Krzemionki is all about.

"Krzemionki" is the name of a former village, but not the name of the current location. The main site lies between the villages of Sudół en Magonie, 8km northeast of Ostrowiec Świętokrzyski. I drove there in 2.5 hours from Warsaw airport. Nowadays it is a wooded area, with some administration buildings and a grand parking. This Saturday afternoon though there were only a few cars. When I bought my entrance ticket (18 zloty / 4.20 EUR), an English-speaking colleague was quickly called for help by the cashier lady. He told me that a tour had just started with a Polish and German speaking guide. After confirming that German is OK for me too, and I could join them immediately.

Together with 4 Polish tourists and guide Kinga I walked further into the forest. Thousands of flint mines lie beneath the ground here. They can be recognized by small ‘dents’ in the landscape, a bit similar to bomb craters. Next to these pits are ‘hills’, the slag heaps. Everything is now overgrown with grass and trees so it is not very visible up and close.

There were 4 types of mining executed here, but they all had in common that they had to reach up to 10 meters deep to reach the veins with flint. This location has 2 veins approximately 1 meter above each other. They were formed when there was a large lake here: trenches made by animals at the bottom of the lake were filled with deposits, which eventually solidified into the rock-hard flint.

As visitors, we were allowed to go underground at the 3rd mine. We descended via an iron spiral staircase, after which we found ourselves in a cool corridor. Also in prehistoric times, the miners connected the various smaller mines with corridors. However, the ones of today have been made with 20th-century visitors in mind so they don't bump their heads.

Flint is still abundantly present in these limestone walls. It was extracted here in an almost industrial way: the flint was brought to the surface and worked there into hammers and chisels. Flint tools that were made here have been found up to 600km away.

Once back at the site entrance there still was the permanent exhibition to visit. It is not immediately obvious where it is (it is in the building marked ‘Tourist Information’), so I asked the guide to show me the way. She subsequently gave me a private tour inside - all accompanying texts are in Polish and she was sorry that I could not read them. Different types of flint from all over the world are shown here. Most of it is characteristically black, whereas the flint of Krzemionki is of the striped variety which only occurs in this region. In polished form, they make for nice souvenirs or even jewelry.
