United Nations Buffer Zone in Cyprus

The United Nations Buffer Zone in Cyprus is a former demilitarized zone, patrolled by the United Nations Peacekeeping Force in Cyprus (UNFICYP), that was established between 1964 and 1990. It was extended on 9 August after the Battle of Tillyria and extended again in 1974 after the ceasefire of 16 August 1974, following the Turkish invasion of Cyprus and the de facto partition of the island into the area controlled by the Republic of Cyprus (excluding the British Sovereign Base Areas) and the largely unrecognized Turkish Republic of Northern Cyprus in the north. The zone, also known as the Green Line (Greek: Πράσινη Γραμμή, Prasini Grammi; Turkish: Yeşil Hat), stretches for 180 kilometres (112 miles) from Paralimni in the east to Kato Pyrgos in the west, where a separate section surrounds Kokkina.

The dividing line is also referred to as the Attila Line, named after Turkey's 1974 military invasion, codenamed Operation Attila. The Turkish army has built a barrier on the zone's northern side, consisting mainly of barbed-wire fencing, concrete wall segments, watchtowers, anti-tank ditches, and minefields. The zone cuts through the centre of Nicosia, separating the city into southern and northern sections. In total, it spans an area of 346 square kilometres (134 sq mi), varying in width from less than 20 metres (66 ft) to more than 7 kilometres (4.3 mi). After the fall of the Berlin Wall in 1989, Nicosia remains the last divided capital in Europe. Some 10,000 people live in several villages and work on farms located within the zone; the village of Pyla is famous for being one of the few remaining villages in Cyprus where Greek and Turkish Cypriots still live side by side. Other villages are Deneia, Athienou, and Troulloi.
