1.25 Euro Sant Joan de Caselles

Andorra began issuing its own coinage only after a 1978 agreement formalized the principality's monetary arrangements, though it lacked full EU membership and struck coins primarily for collectors rather than general circulation. The Sant Joan de Caselles series draws on one of the country's most photographed pre-Romanesque structures, a church whose square bell tower dates to the eleventh century and survived largely intact due to the valley's geographic isolation rather than any deliberate preservation effort.
