0 Euro - Millau - Viaduc

The zero-euro souvenir note was a French commercial concept launched around 2015 by UECQ and printed by Oberthur Fiduciaire in Rennes — the same security printer responsible for a substantial portion of euro banknote production for the Banque de France. These notes carry no legal tender status anywhere and were sold directly to tourists at the sites they commemorate. The Viaduc de Millau, completed in 2004 and designed by Michel Virlogeux with Norman Foster, was the world's tallest vehicle bridge at the time of its opening, its tallest pier reaching 343 metres.

Oberthur used genuine banknote-grade security paper and incorporated authentic anti-counterfeiting features — an odd choice for a note worth nothing, but commercially necessary to prevent the notes themselves from being used in fraud schemes involving real currency.
