Les Pierres Jumelles

Les Pierres Jumelles are two raw sandstone monoliths located near Mont-Saint-Éloi. The larger stone reaches approximately 3.30 meters high and weighs around 8 tons, with the two blocks standing roughly 8.90 meters apart from each other.

The two stones were excavated by Count Brandt-de-Galametz in 1820, who discovered sandstone coffins containing iron weapons between them. They have held protected historical monument status since 1889.

The site is known locally as the Demoiselles d'Acq, a name rooted in a local tale about young women transformed to stone after dancing. This legend shapes how people in the region understand and speak about these two monoliths.

The stones are located near the village of Écoivres and are accessible year-round. They sit in open countryside, so visitors should prepare for all weather conditions and potentially muddy ground depending on the season.

A historical tradition links these stones to Baldwin I of Flanders, who reportedly erected them in 862 to commemorate his victories against Charles II. This connection to early medieval power adds a layer to the site that extends beyond its prehistoric origins.
