I decided finally to visit this amazing small town which is famous for being built originally amongst the overhanging cliffs and rocks above a small river. The records show that the town was occupied by the Romans about 1,000 years ago, but local cave paintings nearby indicate that this place could have been occupied as long ago as 25,000 years. The Moors later occupied the town but were expelled during the Christian Reconquest in 1484. The castle here dates from the 12th century.
Spain is full of these fascinating places that you can explore at your leisure.
