Hall of Nations was an exhibition hall that was inaugurated in 1972 as part of the Pragati Maidan complex in New Delhi, India. It was built to celebrate 25 years of Indian independence.[1]
Inaugurated by then Prime Minister Indira Gandhi for the India International Trade Fair, it was, at the time the world’s first and largest-span space-frame structure built in reinforced concrete.[2][3] It was part of group of four halls of varying sizes and each interconnected by a system of ramps. They were designed by architect Raj Rewal, who went on to win the Gold Medal of the Indian institute of Architects in 1989.[4]
The building was demolished in 2017, along with Hall No. 1 to 6, 14 to 20, state pavilions, and key neighbouring structures like the Hall of Industries and the Nehru Pavilion to make way for a new exhibition and convention centre.[1][5] It was replaced by Bharat Mandapam.
