I visited Delhi twice, and the difference of these two journeys is 7 years and both the time my experience in Qutb Minar which is located in Delhi and is about 16 kilometres from New Delhi Railway Station.
I saw the surrounding of that place which was quite dirty and this was the fault of the people who visit there and mostly the garbages are lying on the ground such as packets of chips and wrappers etc. There is not a proper security which can handle the visitors. Secondly, I was not able to find a dustbin at their proper place where it's need, which directly questions the management.
One of the most pathetic thing I suffered both the time of visiting is that, I am not able to reach at the top of the Qutb Minar because I got an answer that the Minar is under construction and it's true because I have seen workers working but when I visited again and I was excited to see the sighting of the whole Delhi from the top of the Qutb Minar but again I was not able to reach there because construction work was going on and my sight seeing experience was totally thrashed. There are some more monuments which looks too weak and it's dangerous to have a look of them from near. Here is also a fault of management, where renovation is needed, they are not working on it. Many monuments are effected by natural disasters and time is not far that we will loose our history it these monuments are not maintained. My experience was boring and unsatisfying. Comment about your experience near Qutb Minar. If you found something special.
