Googled АВИА ПАРК Москва
That appears to be a multistory saltwater aquarium. Wow.
Even in the Soviet Era, Москва had ГУМ, pronounced [ˈɡum], an abbreviation of the Russian: Главный универсальный магазин (Grasniya Universalnia Magazine Great Universal Store), which in Moscow, was the largest store in the world. . . but it never had anything to sell.
I have spent many years of my life trying to avoid places like that.
Horrible.
