On the second day, the Erasmus team went on a cultural daytrip to Córdoba. The day started with the visit to La Mezquita
and then the group continued with a tour guide around the city center and The Alcázar. The group of teachers could learn that in 10th-century Córdoba, mathematics—and particularly geometry—was applied to architectural design in new ways, constituting a “mathematical turn” of Islamic architecture. In the mosque of Córdoba and in the palaces of Madīnat al-Zahrāʾ, geometry was employed in the design of ground plans, elevations, decorative patterns, and even to measure the human view.
