Because of its unique history and a remarkable number of religious monuments, Caravaca de la Cruz is considered a significant holy city by the Catholic Church. A tour of the city is best begun with a visit to the medieval Castle of Santa Cruz, once a Moorish stronghold and then the site of several convents and a church. Inside the castle’s church, the famous Caravaca Cross is said to have converted a Muslim ruler to Christianity in the 13th century, and is treasured by believers for its healing powers.
