Holes in the ground mark what has disappeared from a Gallo-Roman site at Saint-Romain-de-Jalionas, in southeastern France. Archaeologist Robert Royet shows the excavations and describes a loss that goes beyond the missing objects: evidence about the past has been removed with them.

France's TF1 INFO follows that damage through online sales, seized collections and a dispute over how metal-detecting enthusiasts should be regulated. Its report, "ENQUÊTE : quand la chasse aux trésors vire au pillage archéologique" ("Investigation: When treasure hunting turns into archaeological looting"), distinguishes a popular hobby from unauthorized digging and commercial exploitation of archaeological finds.

At the Museum of Art and Archaeology in Laon, northern France, director Rémi Bazin presents seized coins and tools. His explanation turns on context: an object removed without scientific documentation loses the information its location and surroundings could have supplied. Recovering the artifact does not recover that evidence.

The report shows archaeological objects offered for sale online and footage of seizures by French police and customs authorities. It explains that digging for objects of historical or archaeological interest requires authorization from the prefect, the state's local representative.

But the final part gives detectorists room to challenge the approach. Thierry, a hobbyist filmed in Bourbourg in northern France, describes his activity as lawful removal of metal waste. He favors a Belgian system for declaring discoveries, arguing that finds can contribute to local history.

Marc Méreaux, president of the French Federation of Metal Detection, argues that France's rules discourage cooperation. In his account, declaring a discovery risks bringing trouble rather than recognition. He rejects treating hobbyists as looters or criminals.

The report closes with an estimate that more than two million objects are illegally unearthed in France each year, underscoring the scale of the heritage loss it investigates.
