La Lamberta Excavated in the molasse, they have 200 meters of galleries. The infantry work intended for the machine gun position is one of the scattered fortifications set up during the First World War to defend the Swiss Plateau. The construction of this infantry work took place between 1916 and 1917 and made it possible to protect the axis of Lake Morat. Today these caves have become a paradise for children for long games of hide-and-seek. https://www.j3l.ch/fr/P8751/lieux/sites-naturels/les-grottes-des-roches-grises-la-lamberta
