Kresty (Russian: Кресты, literally Crosses) prison, officially Investigative Isolator No. 1 of the Administration of the Federal Service for the Execution of Punishments for the city of Saint Petersburg (Следственный Изолятор № 1 УФСИН по г. Санкт-Петербургу) is a detention center in Saint Petersburg, Russia. The prison consists of two cross-shaped buildings (hence the name) and the Orthodox Church of St. Alexander Nevsky. The prison has 960 cells and was originally designed for 1150 detainees. It is slated to be closed after the construction of a modern prison facility (also in the shape of a cross).
