Detail of Granada cathedral

Granada Cathedral (Cathedral of the Incarnation) is the cathedral in the city of Granada. Foundations for the church were laid by the architect Egas starting from 1518 to 1523 atop the site of the city's main mosque; by 1529, Egas was replaced by Diego de Siloé who labored for nearly four decades on the structure from ground to cornice, planning the triforium and five naves instead of the usual three. Most unusually, he created a circular capilla mayor rather than a semicircular apse, perhaps inspired by Italian ideas for circular 'perfect buildings' (eg in Alberti's works). Within its structure the cathedral combines other orders of architecture. It took 181 years for the cathedral to be built.
