The Cascade is a giant stairway made of limestone in Yerevan, Armenia. It links the downtown Ketron area of Yerevan with the Monument neighborhood. Designed by architects Jim Torosyan, Aslan Mkhitaryan, and Sargis Gurzadyan the construction of the cascade started in 1971 and was partially completed in 1980.
Inside the Cascade, underneath the exterior steps, are seven escalators that rise along the length of the complex. There are also exhibit halls connected to some of the landings along the escalators which compose the Cafesjian Museum of Art.
