In the QUTUB MINAR complex, there is not only one but three pillars of significant importance. at first obviously youll see the mighty qutub. its height and the carvings on it will amaze you. its so symmetric and so beautifully detailed. then a few yards away youll see the iron pillar. you wont think much of it because its not that big and doesnt look much. but the amazing thing about it is that its made of iron but it doesnt rust. how did they manage to do that at that time ? then if you go a bit furthur youll see tha Alai minar. Alauddin khilji ordered this pillar to be twice the size of qutub minar. unfortunalety it was never finished due to Alauddin khiljis death. but the base is there and you can imagine what itd look like if it was completed. going on the qutub complex is like killing 3 birds with 1 stone. it is a must see in delhi.
