Seversk was a secret city in the Soviet Union until President Boris Yeltsin decreed in 1992 that such cities could use their historical names. The town appeared on no official maps until then. As was the tradition with Soviet towns containing secret facilities, the designation "Tomsk-7" (like its predecessor "Pyaty Pochtovy") is simply a postal code which implies that the place is located close to the city of Tomsk.
Earlier this week, the city council of Kirov voted overwhelmingly to erect a new monument to Felix Dzerzhinsky, the founder of the Soviet secret police forces. The monument is an initiative by a local group of veterans from the Federal Security Service (FSB), and is being financed with private donations.
Serp i Molot means Sickle and Hammer. The factory is a steel plant that lies to the east of the Centre of Moscow. Take a telephoto lens and some binoculars if you have them.

This is a 'closed site' and as things stand, access is not possible on a casual basis.
