This year marks four decades since the Cyprus National Guard staged a coup that led to Turkish military intervention and escalated the civil war between the Greek and Turkish communities on the island. After the ceasefire, a heavily restricted buffer zone, controlled by the United Nations, was established between the north and south. It stretches 180 km (112 mi) across the whole island measuring 7.4 km (4.6 mi) at its widest and 3.3 m (11 ft) at its narrowest point. The demilitarized zone is restricted to the general public and no Greek or Turkish Cypriots are allowed inside. Reuters photographer Neil Hall recently visited the buffer zone, which still contains crumbling relics of times gone by - abandoned houses, businesses, and even an airport - crumbling snapshots of Cyprus in 1974.
