Originally in this place there were several beautiful Jain and Hindu Temples all together 27. They were all destroyed by Islamic fanatic ruler Qutb-ud-din Aibak and reused the materials for the construction of mosque and minar. This can be seen from the Persian inscription still on the inner Eastern gateway.
All the monuments other than temple ruins were built after 1192 A.D. Some of the important monuments here are:
- Qutb Minar
- Quwwat ul-Islam Mosque
- Alai Minar
- Iron Pillar
- Tombs of Iltutmish, Alauddin Khilji
- Jain Temple Ruins
