0 Euro - Château de Pierrefonds

The zero-euro souvenir note program, administered through licensed distributors across European heritage sites, was formalized around 2015 and has since become an unexpected secondary market in its own right — certain early regional issues now trade well above face value among collectors. Oberthur Fiduciaire prints the series to genuine banknote specification, which means real intaglio work, genuine security thread, and UV-reactive elements, all for a note that was never legal tender by design.

Pierrefonds is a 19th-century reconstruction by Viollet-le-Duc, commissioned by Napoleon III — not a medieval survival, though it reads as one.
