Úbeda's casco antiguo (old town) is one of the most outstanding enclaves of 16th-century architecture in Spain. It's a stunning surprise in the heart of Jaén's olive groves, set in the shadow of the wild Sierra de Cazorla mountain range. For crafts enthusiasts, this is Andalusia's capital for everything from ceramics to leather. Follow signs to the Zona Monumental (Monumental Zone), where there are countless Renaissance palaces and stately mansions, most closed to the public.
