The Yellow Submarine

Bearing the proud name Yellow Submarine, the commune at 28 Primorsky Prospect in Leningrad arose in August 1977 and lasted for just one year. Its organizers were university classmates Alexander Skobov and Felix Vinogradov, who had dreamed about a place where everyone could experience personal freedom, where everyone could distance themselves from the current regime and express themselves freely.
