Spanish Pyrenees Hike ~ Zaragoza (Region) The most important historical precedent of Calatayud is the founding of Bilbilis Augusta, a Roman city and birthplace of illustrious figures such as the poet Martial. The name came from the Arabs who arrived in the area in the early 8th century AD and settled around the Ayyubid Castle (Qal'at Ayyub) on the present site of the city. Its importance continued for centuries, so much so that in the 19th century it became the fourth province of Aragon. Today, it is the county seat and a city of historic sites. Calatayud is located at the foot of a ruined site of five Arab-era castles, considered one of the oldest fortified systems in Muslim Spain. The Ayyubid Castle still retains three octagonal towers and several sections of city walls. The city is home to numerous noble residences and Renaissance palaces. The main square is home to the town hall and the Dolores Inn, named after the legendary woman who inspired the famous "copla" song. #AprilDestinations2025 #SpainTravel #Aragon
