44 Most Underrated Cities You Should Visit In Spain

29. Jaén, Andalusia: Olive Oil Capital Under a Castle

While tourists flock to other Andalusian cities, Jaén remains delightfully authentic. Perched dramatically beneath the Castle of Santa Catalina, the city dominates a landscape carpeted with seemingly endless olive groves – Jaén is the undisputed world capital of olive oil. Visit the impressive Renaissance cathedral (a model for many in Latin America), explore the Arab Baths (some of Spain's largest), and savor tapas where olive oil is king. The views from the castle alone are worth the trip, offering a different perspective on Andalusia.
