1. Aljafería Palace
This fortified Islamic palace comes as a shock to many travelers who associate Moorish architecture strictly with the south of Spain. Built in the 11th century, it stands as the most northern Islamic palace in Europe, serving first as a Hudid residence and later as the palace for the Catholic Monarchs. The exterior is all martial strength—thick walls and rounded towers—but the interior shifts immediately to delicate arches, intricate stucco work, and a peaceful courtyard filled with orange trees that feels miles away from the modern city outside.
Today, the building houses the Aragonese Parliament, creating a rare juxtaposition where modern democracy operates within medieval walls. You will walk through the Golden Hall and the mosque oratory, seeing the specific Mudejar artistry that earned this site UNESCO recognition. The encounter between Islamic delicacy and the heavier Gothic additions made by later Christian kings tells the city's history better than any textbook.
While planning your route through Zaragoza attractions, prioritize this site as it requires a bit more time than the city center stops. It is located slightly west of the old town but is easily walkable. The guided tours are essential for accessing areas that might otherwise be closed or hard to interpret.
