Rostov-on-Don has its own version of Upside Down House, an amusement beloved of kids around the world. Rostov’s Upside Down House, the biggest in the Southern Federal District, opened in the summer of 2015. People with vestibular problems should probably stay away from this topsy-turvy world, where everything is upside down. But the kids are overjoyed. The house tilts 10 degree as you step into it. For a moment it feels like you’re losing the floor or, as it were, the ceiling from under your feet. The project owners plan to rejuvenate the furnishings and decorations inside, in order to make people want to return.
