The Lubyanka Building is the popular name for the headquarters of the FSB and affiliated prison on Lubyanka Square in Meshchansky District of Moscow, Russia. It was previously the national headquarters of the KGB; Soviet hammers and sickles can still be seen on the building's façade. The building's prison is actually located on the top floor, but since there are no windows on that floor, most prisoners, and therefore popular conception, thought they were being detained in its basement.
"My Russian grandfather used to say that Lubyanka was the tallest building in Moscow, because you could see Siberia from its basement."
