Most of the barracks and watchtowers of Soviet prison camps have disappeared because they were made of wood. But in many camps there was one building that was usually of stone – the camp prison. It seems absurd to have a prison inside prison, but such uncanny things were common in Gulag. This former labor camp prison house, or tjurma, is situated at the microraion of Severny at the northern side of Vorkuta, a city which was born out of a prison camp. The building had been in other use after Gulag and now it is abandoned – a true modern ruin that can tell a lot about the recent past.
