In 1907, a small dry stone wall was discovered, along with the remains of a hearth on the floor covered with ashes, charcoal, kitchen debris, and even weapons. Armand Viré, another spelunker, believed at that time that these remnants had been left by soldiers from the Hundred Years' War. In fact, the chasm had been inhabited by people fleeing various wars over the centuries, from the Hundred Years' War to the Wars of Religion.
