0 Euro - Paço dos Duques de Bragança Guimarães

The zero euro souvenir note program, administered by the Musée Européen de la Banknote in Paris and printed by Oberthur Fiduciaire, launched in 2015 as a licensed collector scheme — the notes carry genuine euro security features, including a holographic strip, but have no legal tender status anywhere. Oberthur produces them on the same equipment used for circulating currency, which is precisely the point: the tactile and visual experience of a real banknote is the product being sold.

The Paço dos Duques de Bragança in Guimarães was built in the early fifteenth century by Dom Afonso, later the first Duke of Bragança, and substantially restored under Salazar in the 1930s — a restoration widely criticized by architectural historians for prioritizing political symbolism over archaeological accuracy.
