Recinto amurallado de Calatayud

The fortified enclosure spreads across roughly 4 kilometers around the town and includes five distinct fortified zones, with the Castillo Mayor and Torre Mocha as major structures. A network of five castles strategically positioned on surrounding hills formed an interconnected defense system.

The original walls date from the first half of the 9th century, with the Emiral Gate from 862 standing as Spain's oldest known Islamic architectural element. The fortification was later expanded and reinforced during the Christian period to protect the growing settlement.

The walls show how the settlement transformed from an Islamic town into a Christian city, blending different building styles that reflect this long change.

Three original gates remain accessible: Puerta de Zaragoza, Puerta de Terrer, and Puerta de Soria, which lead into the historical center. Walking the entire perimeter takes several hours, so plan your visit accordingly and wear comfortable shoes.

The Emiral Gate from 862 holds the distinction of being Spain's oldest known Islamic building. Few visitors realize this fortification contains such an ancient architectural treasure from the earliest Islamic period.
