The Australian Paliochora-Kythera Archaeological Survey (APKAS) is designed to investigate the broad question of the relationship between fortified centres and their hinterlands, testing alternative hypotheses for site location and the factors influencing occupation and abandonment of sites. The project focuses on the area surrounding the abandoned site of Paliochora (medieval Ayios Demetrios), in the north-eastern part of the island.
What was the relationship between fortified centres and their hinterlands in the Byzantine period? Were military considerations the pre-eminent concern for location and existence? Why was the site not settled until ca. AD 1000? Why was it abandoned?
