الفتح الإسلامي للأندلس
The archeological excavations in 2006–2007 turned up various remains, including traces of older buildings on the site dating back as far as the 11th century. Two human burials were identified beneath what is now the oratory. They certainly date back at least to the 11th century, and possibly as far back as Roman times, though most likely they date from after the Umayyad conquest of Hispania.
