Cordoba

You can see it all in 3 days, 4 at most, as I did. It's a jewel of Andalusia that deserves to be appreciated calmly and without haste. The old town is a maze of little streets with white walls and cobbled pavements. Visit the Juderia quarter as far as the ancient Arab walls. The Mezquita, with its breathtaking cascade of Muslim arches and its opulent Baroque-Christian beauty, is best visited in the morning: entry is free and you enjoy it more before the hordes of tourists arrive.
