Estimated to be 1,000-feet long, the room is situated on the building’s ground floor. ASI needs permission from India’s Ministry of Culture to drill a hole and investigate the room.
The Times of India has more: “The chamber has lain untouched for over two centuries. Wonder what secrets it holds. The archaeologists who discovered it have no clue either, their theories range from a torture chamber, or a sealed tomb for an unfortunate soul or the most favoured of all a treasure room. Some say they wouldn’t be surprised if both skeletons and jewels tumble out of the secret room.” (Via Maud Newton)
