Christiana (Greek:Χριστιανά) is a group of three volcanic Greekislands in the Cyclades.
The group is located about 10 miles southwest of Santorini and is made up of the islands Christiani (Χριστιανή, the largest one), Eschati (Εσχάτη) and Askania (Ασκανιά). All three islands are now uninhabited but on Christiani there are remains of human settlement dating back to Neolithic times.
