“My introduction to Marrakech came with a jolt—the city opened my eyes to color,” Yves Saint Laurent said after his first journey to the Moroccan city, in 1966, with partner Pierre Bergé. The handcrafted zellige tiles, Zouak wood painting techniques, djellaba robes, and caftan garments he spotted throughout Marrakech deeply inspired the French couturier throughout the 1970s, a time in which he created lavish ready-to-wear garments that now star in a dazzling exhibition at the restored chapel of St. John the Evangelist near the Palacio Cadaval. “The boldness seen since then in my work, I owe to this country,” he said, “to its forceful harmonies, to its audacious combinations, to the fervor of its creativity.”
