The pre-Soviet square was designed by Boris Mehrabyan (Megrabov) in his 1906-11 general plan of Yerevan.
In 2003 the square was renovated and extensive excavations took place at the square.
An older layer—from the 18th-19th centuries—was uncovered.

The current square was designed by Alexander Tamanian within his 1924 general plan of Yerevan.
The construction of the square started in 1926, when the Government House began.
It was developed until the 1950s when the rest of the five buildings were constructed and finally completed in 1977, when the National Gallery was built.
The square was named Lenin Square (Armenian: Լենինի հրապարակ, Lenini hraparak; Russian: площадь Ленина ploshchad’ Lenina) for Soviet leader Vladimir Lenin, whose statue was erected in the square in 1940 and dismantlement in 1991, prior to the independence of Armenia.
