Man-made underground passage in Monavallet

Monavallet holds a man-made underground passage behind an outbuilding, built from dry stone and remembered through local tradition. The stones fit together without mortar, suggesting craftspeople understood pressure, drainage and darkness well enough to keep the way open. People may have stored goods, hidden themselves or simply enjoyed the cool quiet beneath the fields. Whatever the purpose, the passage still belongs to the land and waits for someone curious enough to listen.
