[6] It was completed in January 2019 and unveiled on 25 February 2019 in an inauguration ceremony held at the monument where Prime Minister of India Narendra Modi in the presence of Chief of Defence Staff (CDS) of India, and the three Chief of Staffs of the Indian Armed Forces, ignited the eternal flame of the Amar Jawan Jyoti (Flames of Eternal Soldiers) at the Amar Chakra under the main obelisk of the monument.

[12][1] The chief architect, Yogesh Chandrahasan, of WeBe Design Lab, was inspired by the thought of creating a memorial to celebrate and honour sacrifices as compared to a place to mourn them.

[14] The Memorial has four concentric circles and a central obelisk, at the bottom of which burns an 'eternal flame' representing the immortal soldier (amar jawan).

[5] A National War Museum will be constructed in the adjoining Princess Park area and will be connected to the memorial through an underground tunnel.

The Princess Park is a 14-acres large area north of India Gate, with barrack-like accommodations built during World War II.

In July 2020, the Central Public Works Department opened the tender for the selection of a consultant for the National War Museum in an area of around 10 acre.
