Underground mills, Le Locle

"We’re now in a water mill, an underground mill. A torrent roars deep beneath the ground unbeknownst to everyone above; the water falls from several feet onto the noisy turning wheels that threaten to catch our clothes and take us with them. The steps we’re on are worn and damp; the stone walls are running with water and, close by, the abyss opens."

Hans Christian Andersen, 1836
