This 16C palace built by Andrés de Vandelvira for José Vázquez de Molina owes its name, Palacio de las Cadenas, to the chains between the columns on the square. First a convent, then a prison and finally a town hall, it boasts a beautiful façade emblasoned with a coat-of-arms on which the decoration veers between Andalusian and Classical. Don't miss the elegant double-arcaded patio, or the fine artesonado (coffered) ceiling on the first floor.
