The Potemkin Stairs is a giant stairway in Odessa, Ukraine. The stairs are considered a formal entrance into the city from the direction of the sea and are the best known symbol of Odessa.
Officially known today as the Primorsky Stairs, they were originally known as the Boulevard steps, the Giant Staircase, or the Richelieu steps.
The top step is 12.5 metres (41 ft) wide, and the lowest step is 21.7 metres (70.8 ft) wide. The staircase is 27 metres high, and extends for 142 metres, but it gives the illusion of greater length.
