The RA Presidential Palace was designed in 1951 as the premise for the Council of Ministers of the Armenian Soviet Republic. Later it was serving as the building of the Presidium of the Supreme Council of Armenia.

The building was design by Mark Grigorian - Distinguished Architect of the Armenian Soviet Socialist Republic, Esteemed Art Worker of the ASSR, Laureate of the USSR State Award, the Lenin order awardee. In 1960, Mark Grigorian, the architect of the building was awarded a diploma of the ASSR Supreme Council.

The first floor area of 338m2 and 10m height is a reception area, with detached reception halls.

In 1987, the building was reconstructed according to the design developed by the ArmProject Institute. The edifice was augmented with two 10 m wide and 6 m long three-story structures. After the reconstruction, the area of the structure totals 4470 m2. The façade of the edifice is built of yellowy tuff.

After the establishment of the Second Armenian Republic in 1992, the building was transformed into the Presidential Palace.

By decision of the Government of Armenia, in 2004 26 Baghramian Ave was included in the State Registry of Yerevan Historical and Cultural Immobile Monuments as a monument of state significance.
