0 Euro - Aqueduct of Segovia; coat of arms

EuroSouvenir notes are legal-tender collector issues authorized under a European Central Bank framework that permits eurozone member institutions — and, through licensing, certain non-bank entities — to issue zero-denomination notes as souvenirs without affecting monetary supply. Oberthur Fiduciaire prints the series with genuine banknote security features, including the hologram strip, precisely because the licensing agreement requires production to meet actual currency standards.

The Aqueduct of Segovia is a Spanish national monument, not a eurozone infrastructure symbol, which makes its appearance here a straightforward tourism souvenir rather than anything with deeper monetary significance. Worth noting for what it is, nothing more.
