Did you know that the Hall of Nations at Pragati Maidan, New Delhi, was the first of its kind to be built using reinforced concrete?

Designed by architect Raj Rewal with structural design by Mahendra Raj, the building, according to its makers, was conceived of in terms of the traditional ‘jali’, a geometrical pattern of perforation that serves to obstruct directs rays of the Sun while permitting air circulation. And that’s just one of the magnificent structures that will be discussed as part of The State of Architecture — Practices and Processes in India, a three-month-long exhibition focussed at generating dialogue around Indian architecture.
