Solovetsky Stone (Saint Petersburg)

The Solovetsky Stone is a monument to the victims of political repression in the Soviet Union and to those who have fought and fight for freedom. It stands in Troitskaya (Trinity) Square in Saint Petersburg, near several other buildings directly related to political repression in the Soviet era—the House of Tsarist Political Prisoners; the prison and necropolis of the Peter and Paul Fortress; and the Bolshoy Dom or headquarters of the NKVD, both in the city and the surrounding Leningrad Region.
