Jantar Mantar de-notified as protest site: Who decides where protests can be held?

On October 12, 2026, the Delhi Police announced that Jantar Mantar, a historical astronomical observatory, has been denotified as a protest venue. This decision was based on recommendations from a committee formed by the Ministry of Home Affairs to identify alternative sites for demonstrations.

Jantar Mantar, originally known as Yantra Mantra, was constructed by Maharaja Sawai Jai Singh II of Jaipur in 1724 as an astronomical observatory for Mughal emperor Muhammad Shah. The complex comprises four principal instruments - Samrat Yantra, Ram Yantra, Jai Prakash Yantra, and Mishra Yantra - designed to provide highly accurate readings of astronomical phenomena. These instruments, made of brick and lime plaster, were built to minimize vibrations and accurately track celestial movements.

While initially used for astronomical calculations, Jantar Mantar transitioned into a prominent protest site in recent years. Major demonstrations held at the venue include anti-CEC protests in 2026, the India Against Corruption movement, and the fast initiated by anti-corruption activist Anna Hazare. The site's strategic location, less than 3 km from Parliament, has allowed protesters to closely engage with the political establishment while remaining outside the high-security perimeter.
