The alabaster caves at Xaghra feature stalactites and stalagmites, and have an important place in Greek mythology, particularly the Calypso Cave, overlooking the red sand of Gozo's best beach, Ramla Ihamra. Calypso cave is believed to be the one referred to in Homer's Odyssey as being where the beautiful nymph Calypso kept Odysseus as a 'prisoner of love' for seven years. Two other caves at Xaghra are Xerri's Grotto and Ninu's Grotto, both more impressive than Calypso, but lacking the love story. Below Calypso Cave are the remains of a fortification built by the Knights of St John as a defence bastion.
