"PURANA QILA" Oldest Fort in Delhi, India | Delhi Tourism 4K

Purana Qila (Old Fort) is one of the oldest forts in Delhi. The present citadel at Purana Qila was believed to have been built under Sher Shah Suri. But according to ASI's Vasant Swarnkar, the excavations — the last one was in 2013-14 — point to traces from the 3rd century BC, the pre-Mauryan period.
