A retablo is a devotional painting, especially a small popular or folk art one using iconography derived from traditional Catholic church art. More generally retablo is also the Spanish term for a retable or reredos above an altar, whether a large altarpiece painting or an elaborate wooden structure with sculptures. Typically this includes painting, sculpture or a combination of the two, and an elaborate framework enclosing it. The Latin etymology of the Spanish word means "board behind". Aside from being found behind the altar, "similar ornamental structures are built and carved over facades and doorways", called overdoors.
