Book the big ones before you travel.
Córdoba's most famous monument and a UNESCO World Heritage site. A singular blend of Islamic and Christian architecture, with the forest of red-and-white arches you have already seen a hundred photographs of.
In the heatGo as early as you possibly can, for the heat and for the crowds.
The Casco Histórico — a UNESCO World Heritage quarter of narrow streets, hidden patios, plazas and the unhurried Andalusian atmosphere the city is built on. Walk Calleja de las Flores and Plaza de la Corredera.
The Judería, a medieval district of whitewashed houses and the Córdoba Synagogue. The best corner of the city for lunch and for photographs.
A vast arcaded seventeenth-century square, the only one of its kind in Andalusia, lined with cafés under the colonnade.
A small museum and viewpoint at the far end of the Roman Bridge, with a panorama back over the whole city.
Córdoba's famous flower-filled courtyards, kept by the families who live around them.

The city's other great landmark, looking back across the Guadalquivir to the Mezquita.
In the heatThe photographs are best in the few minutes just before the sun goes.
A historic fortress with terraced gardens, long fountains and Roman mosaics.

The spectacular UNESCO ruins of a tenth-century Umayyad palace-city, and one of the most important Islamic sites in Spain.
