Matrosskaya Tishina legendary prison in Moscow. Matrosskaya Tishina is known to human rights campaigners as the worst of Russia`s infamous pre-trial detention centres, where tuberculosis, Aids and hepatitis are reportedly rife. Originally built as a temporary holding centre for up to 2,500 prisoners, the north-east Moscow building, surrounded by high barbed-wire-capped walls, currently houses 3,500.
