Souterrain du Mehyre — photo spot in Petit-Champoz, 2740 Moutier, Switzerland

Souterrain du Mehyre (Petit-Champoz) is a historic underground network of tunnels and fortification spaces. Photograph cool, moody interior textures—stone, scale, and repeating lines—then step to darker corners for high-contrast silhouettes. Best light is indirect daylight at entrances; inside is dim year-round.more
