Neolithic flint mines of Spiennes

Discovered in 1843, the first excavations were undertaken by the mining engineer Alphonse Briart and two others during railway construction in 1867,[3] with results presented to the International Prehistoric Congress held in Brussels in 1872.[4] Intermittent excavations have been carried out up to the present day.[5]

The Mines of Spiennes cover some 100 ha (250 acres) of downland four miles south-east of the city of Mons. The site is dotted with millions of scraps of worked flint and numerous mining pits, that Neolithic settlers have gradually turned into vertical mine shafts to depths of over 10 m (33 ft). Underneath is an elaborate man-made network of caverns accessible via the many shafts.[2][6]

A seminal stage of human inventiveness, technological and cultural application and progress, the transition between opencast and underground mining for flint nodules is impressively displayed and documented. Research has illustrated Neolithic techniques for the cutting of the flint and the extraction of large slabs of flint, that weighed up to hundreds of kilos. The nodules were extracted using flint picks. The stones were then knapped into rough-out shapes of axes, and finally polished to achieve the final state.

The SILEX'S Interpretive Centre opened in spring 2015.[7][8]

The rough-outs were exchanged over a wide area, about 150 km (93 mi), and were often polished at their destination. Polishing strengthens the final product, making the axe- or adze-head last longer. The smooth surface also aids the cutting action by lowering friction with the wood. The axes were used initially for forest clearance during the Neolithic period, and for shaping wood for structural applications, such as timber for huts and canoes.

The site has been compared with Grimes Graves and Cissbury in the United Kingdom, and Krzemionki in Poland, which are also sources of flint stone. However, different hard rocks were used for the polished stone axes. There are several locations in Britain where fine-grained igneous or metamorphic rock was collected from screes or opencast mines, then roughed out locally before trading on to other parts of the country. Examples include the Langdale axe industry, Penmaenmawr and Tievebulliagh.
