Córdoba in 3 days: the Mezquita-Catedral (the most extraordinary building in Spain: 856 columns, double arches, the most beautiful Islamic mihrab mosaic in the West — then a Gothic cathedral inserted in the center in 1523), the Judería (medieval Jewish quarter — the Synagogue of 1315 CE, the birthplace of Maimonides), the Roman Bridge, Medina Azahara UNESCO palace (the "Shining City" of 936 CE — 10,000 workers, 1,500 mule-loads of marble per day: destroyed in 1010 CE), the Alcázar (where Fernando and Isabel planned the final conquest of Granada and the funding of Columbus), Festival de los Patios (the most flower-spectacular courtyard competition in the world, UNESCO), rabo de toro (bull's tail stew — the most celebrated Córdoba dish), and Montilla-Moriles wine at sunset on the Roman Bridge.
