Recently I have visited Purana Quila and when I watched whats going on there that’s is really awful .You can reach purana quila very easily from Pragati maidan metro station.
When you entre you will see a pond which is totally green due to alage.and unpleasent smell coming out of it The conditon of boat present there is worst.there is no safty for you in pond although thats not big. But it should be maintained.
Inside the purana quila you can see couples kissing each other in public .this is really against culture of India. This is really a beautiful historical place but ther come with other purpose. If you want to visit it with you family plzz dnt.
