The concept of creating cascading waterfalls and terraced gardens between the two parts of the city was first proposed by architect Alexander Tamanyan, who worked on the project of modern Yerevan in the 1920s.

In 1970, 34 years after Alexander Tamanyan's death, the Soviet Union returned to the idea of building the Cascade using the project drafted by the city's chief architect, Jim Torosyan, as well as by Sargis Gurzadyan and Aslan Mkhitaryan.

Torosyan did not fully follow the original plan and made some changes, including the addition of extensive staircases, exhibition halls, courtyards, internal escalators, and various sculptures in the gardens.

The government of the Republic of Armenia decided to reconstruct the existing Yerevan Cascade parts and complete its unfinished sections.

The park features the Mother Armenia statue that houses a military museum dedicated to the history of World War II and the Nagorno-Karabakh conflict.

The entire territory of the architectural heritage is an open-air museum of modern art lying amid the green space.

It is a complex of massive stairs with fountains that rise from the Tamanyan Street pedestrian area in the central Kentron district.

The museum also houses works by many international artists, such as Fernando Botero, Arshile Gorky, Lynn Chadwick, Jaume Plensa, and Barry Flanagan.

[7] Outside the complex, there is a garden integrating works by Britishs sculptor Lynn Chadwick, Barry Flanagan and Paul Cox; Stanislav Libensky and Jaroslav Brychtova (a Czech couple); Jaume Plensa (Spanish Catalan artist and sculptor); and Fernando Botero (Colombian artist).

Classical and jazz concerts often take place at the Cascade during spring, summer and early autumn, with spectators sitting on the steps.
