This sound and light show at the Purana Qila is a beautiful 45-minute program depicting the story of Delhi. I simply loved it! There are 2 versions- in English and Hindi, and costs Rs. 80 per person. I think the timings are 6 PM and 7 PM, not sure. The chairs were arranged in the open air, and the light was projected on the fort walls to recreate the history of the city right from Mahabharata times to current day. The only thing you need to watch out for is the weather- and Delhi being the predictable city that it is, you are almost always safe except the monsoon season, when the show may be cancelled due to rains. The show was quite entertaining and even had lovely musical sequences. The historical setting obviously adds to its charm. I would especially recommend it for anyone wishing to get an introduction to Delhi.
