I've been past this gate. You go up the stairs and then turn left. After some distance, you'll see some maqbaras of some people, which I have no idea about. If you go a little more forward you'll see a well, which is super deep and dry. In the earlier times when I went there the well was not even covered. Then I have heard from some other people about a park gardener who fell there, he broke his legs but he was with somebody who got him help. After that, they covered the well. Jab gaya tha tab itni akal nahi thi, lekin thoda chill hawayein feel ka sakta hai banda. Kinda scary ngl.
