There are three types of prison in Turkey: closed, semi-open, and open. A further distinction is made between ordinary closed prisons and high-security prisons. Many prisons have separate blocks (or wings) for women and some also for children (juveniles), but there are also some prisons which are exclusively for women or children. Prisoners in Turkey must be divided, as per law, into remand prisoners (those being held in pre-trial detention) and convicted prisoners (whose sentences are being carried out). In practice, they are held in the same wards and cells.

History In the Ottoman Empire prisons were called dungeons (zindan). In Turkey, these were mostly dark and damp towers.See the Turkish Wikipedia The first prison was built in Sultanahmet quarter of Istanbul and it was called general prison (Hapishane-i Umumi).Dr. Cevdet YILMAZ: The Historical Castle-Prison of Sinop, published in Eastern Geographical Review, edition 22, page 6.

Besides the death penalty the Penal Code of 1858 included three different types of sentences: rowing on a galley (kürek), pillorying (prangabentlik) and imprisonment in a tower (kalebentlik).See an article of Dr. Mustafa AVCI, accessed on 18 August 2009

The Penal Code of 1 March 1926 (Law 765) made a difference between heavy crimes and corresponding sentences (ağır suç and ağır ceza) and light crimes (hafif suç and hafif ceza). Besides offences (cürüm) there is a separate law on infringements (kabahat). By Law 5349 dated 11 May 2005 the differentiation between light and heavy sentences was lifted.

Between 1980 and 2000

On 12 September 1980 the military seized power in Turkey and the five generals (General Staff) announced martial law in all of the then existing 67 provinces. Members of armed and unarmed left and right organizations that had been engaged in bitter fighting were charged at military courts and in some places held in military prisons. The military prison of Mamak, in Ankara, Metris Prison (in Istanbul) and Diyarbakır PrisonThe website Diyarbakır zindanı offers many details (in Turkish) (often called the hell of Diyarbakır) gained notoriety.

Because of the large number of prisoners new prisons were built. In a report of November 1988, Amnesty International said that the number of prisons had increased to 644 and their capacity had been raised from 55,000 to more than 80,000.AI Index: EUR/44/65/88 (November 1988). See an online edition in pictures Since 1986 relatives of prisoners organized in the Human Rights Association (HRA) or in groups in solidarity with certain prisoners such as TAYAD.Background of the organization on a private homepage, accessed on 27 August 2009 With their help the prisoners tried to make their demands for improved prison conditions for which they frequently went on hunger strikes.

In April 1991 Law 3713 on Fighting Terrorism (called Anti-Terror-Law, ATL) was passed. Article 16 provided that all prisoners charged under this law had to be held in high security prisons.

Since 2000

In 1996 the political prisoners succeeded in their objection to be transferred to the first high security prison in Eskişehir (it was called "special type prison"). Their hunger strike resulted in the death of 12 prisoners. In 2000 a similar action against the high security prisons (now called F-type Prisons) was not successful, although the death toll was much higher.See the page F-type Prisons (Turkey) for further details There are currently 13 F-type prisons (14, if the prison on İmralı Island is added) and two D-type prisons (also high security prisons). The prison population statistics show an immense rise from the year 2000 through 2016. In 2000, the combined number of imprisoned individuals was 49,512. In the year 2016, that number has increased to 200,339. On this date, the rate of incarceration was 285 prisoners per 100,000 Turkish residents. In November 2018, the total incarceration rate increased to 260,000 people. This number incorporates pre-trial convicts. The prison population rate is 318 people per 100,000 of the national population. An estimated national population of November 2018 is 81.68 million. The maximum space of the prison system is 220,000 possible detainees as of November 2018. As of November 2018, the occupancy level is at 118.2%, 18.2% over capacity.

The Human Rights Foundation of Turkey has included such figures in their annual reports.The statistics of the General Directorate for Penal and Arrest Centres start in 1970 at the address http://www.cte.adalet.gov.tr/istatistikler/yillar1.asp. The pages are ordered for 10 years each so that the years 2000-2009 can be found at "yillar4.asp".
