The lower-key but equally medieval counterpart to the Serranos towers, marking the western edge of the old city. Built in the mid-15th century in a heavier military style — squat, round, and fortress-like rather than slim and ceremonial. From the top there is a fine view down Calle Caballeros toward the cathedral.
Climb is included in a small admission fee, free on Sundays. Combine with a walk through the El Carmen quarter on your way back into town.
