Iglesia de la Purísima Concepción y Pósito de Aldeaquemada Monument · Aldeaquemada, Sierra Morena, Jaén Image of Aldeaquemada, not of the place itself. The Iglesia de la Purísima Concepción, from the 18th century and built in Enlightenment colonial style, with a single nave and a brick façade, stands on Aldeaquemada's square next to the old Pósito de Diezmo y Labradores, an 18th-century building with arcades that served as a grain store and is now the town hall.
