Air force cadets yesterday attended the groundbreaking ceremony for new buildings at the Air Force Academy at the Dhekelia air base north of Athens yesterday. The 10.5-billion-drachma construction works are to be completed in 36 months and will include an administration center, a lecture hall, professors’ offices, a small amphitheater and a canteen. The overall project will cover 20,000 square meters. The walls of two classical buildings emerged in trial trenches 800 meters from the sea, under two meters of dark sediment from a lagoon. This bears out ancient descriptions of Helike being visible underwater up to five centuries after its destruction in 373 BC.
