1.5 Euro Castle of Manzanares el Real

Manzanares el Real was begun in the 1440s under Íñigo López de Mendoza and completed by his son Diego Hurtado de Mendoza, second Duke of the Infantado — one of the most powerful noble families in fifteenth-century Castile. It is among the best-preserved late Gothic castles on the Iberian Peninsula, largely because it saw almost no military use after construction, spending much of its history as a ducal residence rather than a fortress.

The 1.5 euro denomination is Spain's standard vehicle for its ongoing architectural heritage series, issued for domestic collector circulation rather than everyday use.
