Rocher Branlant de Largeasse (Jardin des Chirons)

Largeasse

Dimensions
Around 2 m high, 10 m in circumference, some 30 tonnes
Period
Granite chaos of the Armorican Massif, a very ancient geological formation; legend of the stone of justice handed down orally; site saved and opened to the public in 1991
What stands there
30 tonnes that a single person can set rocking, given the right rhythm

In the bocage of the Gâtine, the Sèvre Nantaise flows between granite boulders that the locals call chirons, rounded masses of rock brought to the surface as the surrounding gravel weathers away. The most famous is the Rocher Branlant, a monolith of around 30 tonnes, two metres high and ten metres round, so finely balanced that human strength alone is enough to set it rocking: it is all a matter of angle and rhythm, not of power. Local tradition makes it a stone of justice, or judgement stone: women accused of adultery could reportedly clear themselves by managing to shift the block. The tourist bodies that pass on this story are careful to leave it open, somewhere between ancient custom and reconstructed legend. The site, long in private hands and under threat, owes its preservation to Marie and Gérard Abélard, the latter mayor from 1989 to 1995, and it has been open to the public since 1991. The commune still owns and maintains it, today with a summer programme (concerts, open-air cinema, markets). The spot is also popular for bouldering and for the remarkable tree that grows between the rocks.
