Black Dolphin Prison
correctional facility in Russia
Federal Governmental Institution - Penal Colony No. 6 of the Federal Penitentiary Service of Russia in Orenburg Oblast, commonly known as the Black Dolphin Prison (Russian: Чёрный дельфин, romanized: Chyorny delʹfin) and formerly known as NKVD Prison No. 2 is a prison in Sol-Iletsk, Orenburg Oblast, Russia, near its border with Kazakhstan. It is one of the oldest prisons in Russia, and one of the first in the Orenburg Oblast to accept prisoners with life sentences. It gets its unofficial name from a prisoner-constructed sculpture depicting a black dolphin, which is set in front of the main entrance.
Originally, Black Dolphin was a jail (ostrog) for those sentenced to life at hard labor, since at least 1745. After the suppression of Pugachev's Rebellion in 1773, the prison was updated for the deportation and confinement of robbers. The prison houses approximately 700 inmates convicted of grave offenses, including sexual violence against minors, homicide, terrorism, and cannibalism. Prisoners at Black Dolphin are all serving sentences of life imprisonment. The prison began accepting these inmates on November 1st, 2000.
