Text of a notice on site: THE HISTORICAL SINOP PRISON: "The encircling wals of Sinop had been built by the Seljukians after the conquest of Sinop in 1214. Today's prison is located in the inner castle which was built in 1215 with the contribution of the commanders who took part in the conquest of the city. The inner castle was formed by constructing a wall in North-South direction with the main castle. The materials which were used to build the wals and the towers reflect prehistoric (sic) architecture. The castle as a whole seems (sic) to be an open air museum. The inner castle which surrounds the prison is supported by 11 towers. The height of the towers in South, by the sea side, is 22 meters. The height of the walls is 18 meters and the width of the walls is 3 meters. The inner castle was divided into 2 sections with a wall in East-West direction. The historical Sinop prison was actually built in the Southern part of the inner castle by the Governor Veysel Pasha in 1882. The building has a "U" shape and two floors and its walls were built in cut stones and there are plenty of windows on each wing. The unit on the East wing which faces to the back yard has got 28 wards. On the East wing there is also a steam bath which was built at the same time of the prison. In the North wing there is a unit for delinguent juvenile which has two floors and nine wards, built in 1939. There is also a two storey building in which there are prison cells on the North side of the delinquent juvenile section. All three construction resemble a complete complex from architectural point of view. As a result of a rebellious action of the prisoners in 1979 the main building was partly damaged by a great fire. Some of the famous people who were imprisoned here are Refik Halit Karay, Mustafa Suphi, Ahmet Bedevi Kuran, Refil Cevat, Burhan Felek, Sebahattin Ali, Kerim Korean, Zekeriya Sertel. The building which was given to the Ministry of Justice to be used as a prison for a long time was handed over to the Ministry of Culture in 1999 to be used for cultural purposes.
