The construction of Monas proceeded in three stages.
The first period, from 1961/1962–1964/1965 began with the official start of construction on 17 August 1961 with Sukarno ceremonially driving in the first concrete pile.

A total of 284 piles were used for the foundation block.
A further 360 piles were driven in for the museum foundations, with work being completed in March 1962.
The walls of the museum in the base were completed by October.
Construction of the obelisk then commenced and was finished in August 1963.
Work in the second stage, from 1966 to 1968, was delayed by shortages of funding and the aftermath of the 30 September Movement coup attempt.

In the final phase, from 1969–1976, the dioramas for the historical museum were added.
Problems remained once construction was complete, and work was needed to solve problems with water leaking into the museum.
Monas was officially opened to the public on 12 July 1975.

The location of Monas is known as Merdeka Square.
