On the recent trip to Dharamashala, I had a day's stop over in Delhi. We utilised this to see the Qutub Minar. This is one of the 3 UNESCO world heritage sites in Delhi. The other 2 being Humayun's tomb and the Red Fort.
This is the world's tallest brick minaret. The construction of this minaret was started by Qutb-ud-din Aibak who won Delhi from the Prithviraj under Muhammad of Ghori. It was subsequently extended by Iltutmish and Alauddin Khilji.
Tomb of Iltutmish
The complex has a number things to see like the Ashoka Pillar, Tomb of Iltutmish, Tomb of Alauddin Khilji and the Alai Minar. The ASI has installed an audio guide system in this complex. It is available in multiple languages. Different places in the complex are marked with numbers. On pressing that number in the audio guide, you get the information for that particular place. This is a must-try for the visitors to the complex.
Other places of interest near this complex are the Jain Temple and the Lotus temple.
