IRN Full Form
Built by the British, IIAS is primarily the summer retreat of the Indian President. It was passed on to the nation by the then president – Dr. Radhakrishnan as an institute to promote advanced studies in humanities and arts in India. The building is a classical architectural design with a proficient fireproofing system. A visit to the institute is actually a walk through modern Indian history, which is why it is among the best places to visit in Shimla.
