4Potemkin Stairs
The Potemkin Stairs are located in the city of Odessa. This large stairway features 192 sandstone steps and a number of landings. It was designed to create an unusual optical illusion: when viewed from the top, only the landings are visible. When viewed from the bottom, the landings are hidden from sight and only the steps can be seen. These stairs may be most famous for their appearance in the 1925 movie The Battleship Potemkin.
