Sometimes individuals make archaeological discoveries, for example using a metal detector. However, archaeological remains are the property of the canton where they have been found and the use of these instruments is strictly regulated in Switzerland.
In 2024, the Valais cantonal police seized a collection of archaeological objects in an individual who prospered the soil with a metal detector. An investigation was opened for “serious offense to the federal law on the transfer of cultural goods”.
Another example in 2017, where a man found a 3500 -year -old bronze hand in the Bernese Jura, also using a metal detector. Even if he had immediately given his find to the cantonal archaeological service, he was sentenced to a fine of 2,500 francs. The reason: the use of the detector, prohibited outside a scientific framework.

Not touch
But what to do then in the event of an archaeological find? “It is important not to move the object. The context in which it was found makes it possible to understand it,” explains Caroline Brunetti, Cantonal Archaeologist Valaisanne, in the program we talk about it.
“Ideally, you should take a photo by placing an ordinary object next to it, like a pen. This allows you to assess its size. You can also record GPS contact details with your phone and take some photos of the surroundings.” The specialist recommends carrying out these procedures via the Icewatcher application, which recalls the procedure to follow and directly sends the photos taken to the cantonal offices of Valais, Vaudois or Bernese archeology.

A risk of criminal prosecution
What if we keep the object, what does it risk? “Criminal prosecution. This treasure hunt is actually looting. It is dramatic, because all these objects lose their archaeological value once it is removed from their context. These pieces belong to the cantonal heritage, even if they are on private property”, specifies Caroline Brunetti. “If they are not restored by professionals once digested, they deteriorate and end up dust.”
In Valais, the use of metal detectors is prohibited. But if a scientific project is proposed in which individuals can participate, supervised by an archaeologist, a permit can be awarded. In Friborg and Berne, amateurs are invited to contact the archeology service to receive an authorization after having followed a training.
