A 15-ton iron monument of Dzerzhinsky, which once dominated the Lubyanka Square in Moscow, near the KGB headquarters, also became known as "Iron Felix" ( - "Zheleznyj Feliks"). Sculpted in 1958 by Yevgeny Vuchetich, it served as a Moscow landmark during late Soviet times. Symbolically, the Memorial society erected a memorial to the victims of the Gulag (using a simple stone from Solovki in the White Sea) beside the Iron Felix statue on 30 October 1990. The Moscow Soviet (Mossovet) had the Dzerzhinsky statue removed to the Fallen Monument Park and laid on its side in August 1991, after the failed coup d'état attempt by hard-line Communist members of the government. A mock-up of the removal of Dzerzhinsky's statue can be found in the entrance hall of the International Spy Museum in Washington, D.C.
