The iron pillar of Delhi, located in the Qutub complex, is an important testimony of the history of metallurgy of India. The pillar, almost seven meters or 22 feet high and weighting more than six tons, was supposed to have been created at the times of Chandragupta II Vikramaditya (375-413 AD). It is the remaining piece of a Hindu and Jain temple complex which stood there before being destroyed by Qutub-ud-bin Aybak to build the Qutub Minar and Quwwat-ul-Islam mosque Qutub built around it when he had the mosque constructed.
