In the late 1980s, at the height of Perestroika, CHA began holding lavish exhibitions by artists such as Francis Bacon, Giorgio Morandi, Jannis Kounellis, Robert Rauschenberg, and James Rosenquist. Sculptures by Western modernists appeared in the adjacent park. The winds of change were blowing. On August 22, 1991, the statue of Felix Dzerzhinsky was dismantled and brought to the park. The Communist Party was banned the next day. Busts of Lenin, and statues of Kalinin, Sverdlov, and Stalin from across Moscow started to pile up on the grass. Sculptures were brought in from shuttered sculpture factories, Soviet-era workshops where anonymous artisans manufactured figurines.
