The Clay City in the Woods: Inside the Grande Citadelle de Monthoux
Half an hour from Morges, on the road up to the Marchairuz pass, a fantastical medieval metropolis rises out of the forest floor — gothic spires, bridges, dragons and hermits, all modelled by hand from river clay. It looks like AI-generated concept art. It is real, it is free to visit, and it is still growing.
