CATHÉDRALE DE BAYONNE

Euro Souvenirs are a privately issued collectible format sold at tourist sites across Europe — not legal tender, not redeemable, and not regulated by the ECB. Oberthur Fiduciaire produces them using genuine security printing techniques, which gives them a finish closer to a banknote than a postcard, even though their function is purely commemorative. The Bayonne Cathedral edition falls into a growing catalog of French architectural subjects that Oberthur has been steadily expanding since the format gained traction in the early 2010s.

Bayonne's cathedral, begun in the thirteenth century, sits in the Basque Country and spent centuries under English Plantagenet administration before returning to French control in 1451.
