St Petersburg's memorial to victims of political repression in the Soviet Union takes the form of a large boulder from the Solovetsky Islands. It is symbolic as the very first Gulag camp was set up on these island, but it is nevertheless rather underwhelming considered the scale of the repression. The boulder was placed here in 2002. Previously the wooden Trinity Petrovksy Cathedral, which was founded by Peter the Great in 1709, stood here until it was destroyed by the Bolsheviks in 1933.
