The underground mills of Le Locle showcase 17th-century water-powered milling. Visitors explore tunnels, ancient mechanisms, and flowing water, uncovering a unique piece of history. Then, during the afternoon, you will have the possibility to visit La Chaux-de-Fonds, a near town, and then join for the inauguration of a new exhibition at the Art Museum of La Chaux-de-Fonds (there is going to be a free aperitif!).
Don't forget to take good shoes, warm clothes and your lunch with you !
