Rocking stone of Huelgoat, Rocking stone in Huelgoat forest, Finistère, France.
This porphyritic granite formation measures seven meters long and three meters high, weighing one hundred thirty-seven tons in precarious balance on its base.
Natural erosion processes that occurred several thousand years ago under a humid tropical climate created this remarkable unstable equilibrium through geological weathering.
Breton legends tell that the giant Gargantua threw these rocky blocks in revenge after receiving an insufficient meal in this region of Brittany.
Visitors can make the stone oscillate slightly by applying pressure at the right spot with their back against the rock surface using proper technique.
This bluish-white granite monolith rocks under minimal force due to its unstable equilibrium position resulting from thousands of years of natural erosion.

Throughout France, stone silhouettes still stand in fields, forests, or by the sea. They existed long before villages and roads, witnesses to a world that believed in the sky and hidden forces of the earth. These menhirs, erected over five thousand years ago, in their own way narrate the dawn of civilizations. Some are solitary, others are arranged in rows of hundreds. Some bear engraved faces, others remain silent, smoothed by Breton winds or the rain of the Central Massif. From Carnac to Corsica, from Poitou to the Côtes-d’Armor, these upright stones maintain a strong presence, almost human. Approaching them, one senses the ancient connection between human hands and the memory of the land.
