Equipped with a digital key, you have access to a number of less well-known locations around the castle and the old town, with animation, sound and light displays at some of the sites. It’s also possible to book a guide for the activity.
With your master key in hand, open the doors to some of Porrentruy’s more secret and unusual locations where you’ll enjoy some thrilling animations. Do you know the story of Pierre Péquignat, the rebellious civil servant who defied the prince-bishop, and the tragic end to his fight? Have you ever seen the Vouivre – the fantastical, mythical animal which feeds on the energy of the water – come to life in front of your eyes? Do you think dinosaurs still haunt the town of Porrentruy? On the secret circuit you’ll enjoy a unique and exclusive experience.
