I had visited here on 22 dec , 2018 with my family so I was so bored because here nothing special for visting and it is not the best palace for visit old fort was so boring for me and its my personal experience which was so unimpressed but yaa I remember that experience of chhidiya ghar ( zoological park ) which is near of purana qila , I think chhidiya ghar is best than the purana qila for visiting and the exprience was so great of zoological park because there are most animals , birds and most attractive animals are there so everything is fine to see so I think zoological park is best to visit than the purana qila.
