Zaragoza was once a Roman town called Caesaraugusta. The Moors did not change the name, but pronounced and spelled it as Saraqusta, and afterwards the Romance and Spanish speakers transformed it into Zaragoza. To the west of the city, within the 90 km radius, lies the municipality of Illueca, with just over 3000 inhabitants. Illueca has a strong shoe making tradition - in the 17th century there were already three tanneries in the town. The modern shoe making industry was launched in the 1920s. By the 1940s numerous shoe making factories were flourishing, some of which still exist today.
