Some cities, such as Perm, were opened well before the fall of the Soviet Union; others, such as Kaliningrad and Vladivostok, remained closed until as late as 1992.
Неки градови, попут Перма, су отворени и пре распада Совјетског Савеза, а други, попут Калињинградa и Владивостока, су остали затворени све до 1992.
