CalatayudThe town of Calatayud is located on the bank of the Jalón River, in the south of Zaragoza Province. Some of the high-speed trains that run between Madrid Puerta de Atocha – Almudena Grandes (1:30 – 2:00 hours) and Zaragoza – Delicias (0:20 – 0:30 hour) stations call at Calatayud. Beyond these stations, trains may call at several cities. It takes about 20 minutes to walk from the station to the historic centre.

Calatayud is about four kilometres from the Roman town of Bilbilis, the birthplace of Roman poet Martial. The name of the present town derives from the oldest remaining Arab fortifications in the Iberian Peninsula. The Qal'at Ayyub (citadel of Ayyub) was an eight-century citadel that was extended in the ninth century. The citadel had five castles located on hills overlooking the town. At the highest point stood the Castle of Ayyub, that is the best-preserved part of the citadel.

The judería (Jewish Quarter) of Calatayud was the second-largest in Aragón and almost as big and populated as that of Zaragoza. Its narrow streets preserve the remains of what was the main of several synagogues. This had separate entrances for men and women.

The town has two collegiate churches. The Royal Basilica – Collegiate of the Holy Sepulchre, originally, was built in the twelfth century. The present church dates to the early seventeenth century. It preserves remains of its Mudéjar cloister from the fourteenth century. It is the main temple of the Order of the Holy Sepulchre in Spain.

The collegiate church of Santa María la Mayor was first built on the site of the main mosque, in the twelfth century. The current church was built between the fourteenth and sixteenth centuries. It preserves several Mudéjar elements. The most visible are its 70-metres high octagonal tower and its apsis. The Mudéjar cloisters that house a museum of sacred arts are oriented towards Mecca. The church is part of the Aragonese Mudéjar that was listed by UNESCO as World Heritage.

Its main portal dates to the sixteenth century. It was executed in the Plateresque (Renaissance) style that mimics an altarpiece.

The town has a few more Mudéjar church towers. Among these is that of the Church of San Andrés that stood next to one of the entrances to the Jewish quarter.
A couple hundred metres outside the old town, in Calle Glen Ellyn (named after Calatayud's twin town in Illinois), is the post office. If I counted correctly, this is the 100th post office of which I posted a picture.
