Sacra Capilla,Commissioned by Francisco de los Cobos y Molina as his family's funerary chapel, it presents a marked contrast between the relatively sober proportions of the interior (by Diego de Siloé, architect of Granada's cathedral) and the more decorative western facade. The facade, a pre-eminent example of plateresque style, was designed by Andrés de Vandelvira, one of Siloé's stonemasons, who took over the project in 1540.
