On a corner of the Plaza Mayor rears the solid presence of the 16th-century Palacio de los Duques de San Carlos, nowadays a convent for the Jerónimo order, but open for visits and for selling its homemade biscuits. Its treasures are the sober classical patio and a grand granite staircase crowned with a painting of the family crest: a two-headed eagle. The distinctive brick chimneys were built in Mudéjar style.
