Fodor's Expert Review Iglesia de Santa Cruz
This rather plain church dates to the early 13th century. One of the first built here after the Reconquest, it's also one of the earliest Christian churches in all of Andalusia. It has two Romanesque portals and a curved stone altar. Volunteers oversee admissions to the church, so opening hours can be erratic—you're most likely to find it open in the morning (11–1).
