The Neolithic flint mines of Spiennes constitute a vast flint extraction and knapping center covering around a hundred hectares. They were exploited for almost two millennia between 4350 and 2300 BC. They have been included on the UNESCO World Heritage List since 2000. Find all the information here: minesdespiennes.org

The museum from 2015, built on top of several prehistoric mine shafts (up to 15m deep), can be visited individually (€6/pp; free with MuseumPass). If you also want to descend into one of the mine shafts via ladder (only at 2 pm), you must book this at least one day in advance at the Bergen tourist office, info on the website. Cost: €8/pp on top of museum admission. But for this you get a detailed tour from the excellent guide (we had a perfectly trilingual FR-NL-EN!) First above ground through the museum and then underground. Attention: maximum group of 12 people and children under 10 years not allowed.

It is at the confluence of the Trouille and the Nouvelles river that this waterfall bridge was born. Originally there was a mill, which was turned into a tannery after the First World War. Today it is a bucolic place surrounded by nature.

The Moulin de Spiennes was the village's mill and was founded before 1626 to grind grain. In 1754, the Count of Berlaimont, Lord of Spiennes, owned the mill. He invoked the banality of this mill, basing himself on an act from 1526. According to the Land Registry Atlas PC Popp (ca. 1860), the "meal water mill" stood on plot section B no. 216 and was in the possession of De Glymes, Count Henri-Nicolas, owner, Harmignies. Later in the 19th century there were important changes: the building was raised higher (6 floors) and the water wheel was replaced by a turbine. There are currently apartments located in the fairly high building. https://www.molenechos.org/molen.php?number=637

The enormous size of the site (nearly 100 ha), its age and its archaeological richness have led to the Spiennes site being recognized as a UNESCO World Heritage site in December 2000. This puts the Neolithic flint mines of Spiennes next to buildings such as the Great Wall of China, the Taj Mahal in India or the cemetery of Machu Picchu in Peru. So it is worth driving by! https://www.visitmons.nl/uitstap-naar-een-vuursteenmijn
