0 Euro Maison Carrée de Nîmes

The zero-euro souvenir note was conceived in 2015 by Richard Faille, a French entrepreneur, as a legal-denomination collector item exempt from counterfeiting law — since reproducing a note of zero value defrauds no one. Oberthur Fiduciaire prints them to full security-paper specification, including genuine eurion constellation patterns and UV-reactive inks, which makes them technically more sophisticated than many circulating issues from smaller nations.

The Maison Carrée in Nîmes is among the best-preserved Roman temples anywhere in the world, having survived largely because it was continuously repurposed — as a church, a stable, a private residence, and eventually a municipal archive before becoming a monument.
