    The Spiennes site

    The men who started to dig mines in Spiennes, some 6 000 years ago, are regarded as the oldest miners in the world. They had just discovered a profuse deposit of quality, which was to be exploited for more than 1 800 years. In total, around one hundred hectares were to be exploited and thousands of shafts were to be bored.

    Step by step, mines have replaced pits, from 8 to 11 metres deep. The flint layers are extracted by digging short galleries, from 2 to 5 metres long, which go off from the shaft that gives access to the mines. A mining site, which is 16 metres in depth , has even been discovered to a place called "Camp-à-Cayaux". Large pieces of flint, of around two metres long, have been extracted there with a special technique called "foudroyage".

    The Neolithic mines in Spiennes clearly show, as it is the case with others monuments registered in the UNESCO List, the human beings’ inventiveness. The archaeological potential of the site is considered as a fund of knowledge for the coming generations and is worth protecting for these ones.

    The visit

    "... Right now, we’re going down in the mines". And a guide of ours in Petit-Spiennes will reveal how to reach a mine. You’re sure to shudder as you lean toward the ladder which is 8 metres in depth but, unfortunately for you, it is the only way possible to get to this treasure left by prehistory...

    Arrived at the bottom of the ladder, you’ll find yourself in an "out of time space". You are seized with an amazing feeling, something you’ve never felt before, your thoughts wander and you feel like discovering the place where you are. The site our guides would like you to visit is not a cave, but flint mines dug by our ancestors, by means of flint picks and red deer antlers.

    You don’t visit one single mine but half a dozen of mines which fit in in a way you might consider as a bit incoherent. This small labyrinth leads you to a depth of 10 metres thanks to short galleries - which are also generally low and narrow.

    The mines in Petit-Spiennes are not just an underpass rooted in the past. The mining techniques used by our ancestors seem quite fresh, the marks left by the picks in the chalk seem so recent that one can believe them to have been made a little time ago.
