İmralı is a small Turkish island in the south of the Sea of Marmara, west of the Armutlu-Bozburun peninsula within Bursa Province. It measures 8 kilometres (5 miles) in the north-south direction with a width of 3 kilometres (2 miles), and has an area of 9.98 square kilometres (3.85 sq mi). The highest peak is Türk Tepesi at an altitude of 217 metres (712 feet) above sea level. It is currently a prison island, so it is prohibited to fly over the island or fish near its shores.
The island name derives from its conqueror, Emir Ali, one of the first Ottoman admirals. The island was the first captured by the Ottomans and enabled control of the Sea of Marmara with a naval base established on it, cutting the Byzantine Empire's connection to Bursa.
In 1913 the island had 250 houses, a school, three monasteries, and 1,200 residents, all of whom were Greeks. The economic activity of the island's residents consisted mainly of fishing and farming onions, with most of the grown onions sold to Istanbul. There were three Greek villages on the island until the Turkish War of Independence (1919–1923), engaged mostly in growing grapes, winemaking, silk production and fishing. The island was mostly uninhabited from the 1923 population exchange between Greece and Turkey until 1935, when a semi-open category prison was built. The prisoners earned money by working in agriculture and fishing.
There is also a military base on the island, and the area around the island is a forbidden zone. It served from 1999 until 2009 as a maximum-security prison island for its only inmate, Abdullah Öcalan the leader of the PKK which has been declared a terrorist organization by the USA and the EU. The other prisoners on the island were transferred elsewhere so that Öcalan would be the island's sole prisoner. In November 2009, several other prisoners were transferred to a newly constructed prison building on the island, where Öcalan is also incarcerated.
