"The great mosque of Córdoba was begun by the Muslim caliphs in the eighth century, its forest of pillars and red-and-white striped arches meant to convey a powerful sense of the infinite. With the Christian reconquest of Spain in the 13th century, it was consecrated as a cathedral.
Today, signs throughout this whitewashed Andalusian city refer to the monument, a Unesco World Heritage site, as the “mosque-cathedral” of Córdoba. But that terminology is now in question. Last month, the bishop of Córdoba began a provocative appeal for the city to stop referring to the monument as a mosque so as not to “confuse” visitors."
