The Conventico Caves are located in Melilla, Spain. The Phoenicians, whose territory stretched around the African side of the Medertarian Sea, supposedly excavated these limestone caves. Later occupiers expanded the caves, so they now constitute three levels. Besides the Phonesians, subsequent occupiers used the Conventico Caves as a storage room, refuge during sieges, and a place of worship during wartime. Today, the caves are open to the public every day of the week, and they are well maintained.
