The Museo de Jaén sits on the north side of the old town near the Plaza de las Batallas. Its archaeology department is one of the most important in Andalusia, with the entire ground floor given to the Iberian sculpture from Porcuna — a pre-Roman necropolis whose carved warriors and griffins are among the finest things of their kind anywhere.
There is also a strong Roman section, a fine-arts department upstairs with Spanish Baroque painting (including works by Pedro Berruguete), and a small but well-presented Islamic collection. Free for EU citizens; allow at least two hours.
