Calatayud (2012 pop. 21,174) is a municipality in the Province of Zaragoza, within Aragón, Spain, lying on the river Jalón, in the midst of the Sistema Ibérico mountain range. It is the second-largest city in the province after the capital, Zaragoza, and the largest town in Aragón other than the three provincial capitals. It is the seat of the comarca of Calatayud.
The city has the title Muy noble, leal, siempre augusta y fidelísima ciudad de Calatayud ("The very noble, loyal, always august and most faithful City of Calatayud").  Calatayud became the first democratic municipality in 1977, because elections were held one day before all the rest of Spain, to prepare for a visit by King Juan Carlos I.
Highways and railways 
The city was founded on the site of a Celt-Iberian settlement by the Romans with the name Augusta Bilbilis and was the birthplace of the poet Martial in 40 CE. The site of the ruins of Augusta Bilbilis are approximately four kilometers to the north of the modern city of Calatayud. The modern town was founded by the Moors around the Ayyub castle, circa 716 CE.
The name Calatayud came from the Arabic Qalat 'Ayyūb = "Ayyub's fort". The ancient inhabitants of Bilbilis moved to the new site. Occupying a strategic placement between the central meseta of Spain and the Ebro valley the city retained its importance in succeeding centuries. By the eleventh century a substantial Jewish community was present, surviving the reconquista until the expulsion of the Jews from Spain in 1492. The city was re-conquered from the Muslims by Alfonso I of Aragón in 1119. Many surviving examples of mudéjar church architecture show that the Moorish influence lived on.
During the Peninsular Wars a notable siege of French occupied Calatayud led to its capture by guerillas in 1811. The city was the capital of its own province in 1822–23, during the Trieno Liberal.

One of the most notable Mudéjar towers of Aragón is the 15th century bell tower of the collegiate church of Santa María, which was built on the site of a mosque. The Muslim fortress is the biggest and oldest of the Muslim fortresses of the Iberian peninsula. The church of "San Pedro" was founded by Ferdinand II of Aragón and it was there that the first Cortes (Parliament) of Aragon was held in 1411.
