IRON PILLAR , QUTAB COMPLEX, NEW DELHI

The iron pillar of Delhi, India is a 7 meter (22 feet) high pillar in the Qutb complex which is notable for the composition of the metals used in its construction.
The pillar—almost seven meters (22 feet) high and weighing more than six tons—is said to have been fashioned at the time of Chandragupta II Vikramaditya (375–413), though other authorities give dates as early as 912 BCE. The pillar initially stood in the centre of a Jain temple complex housing twenty-seven temples that were destroyed by Qutb-ud-din Aybak, and their material was used in building the Qutub Minar and Quwwat-ul-Islam mosque. The pillar and ruins of the temple stand all around the Qutb complex today. The pillar is 98% pure wrought iron, and is a testament to the high level of skill achieved by ancient Indian ironsmiths. It has attracted the attention of both archaeologists and metallurgists, as it has withstood corrosion for over 1600 years in the open air.
The name of the city of Delhi is thought to be based on a legend associated with the pillar.

Detail showing the inscription.

The pillar bears a Sanskrit inscription in Brahmi script which states that it was erected as a standard in honour of Lord Vishnu. It also praises the valor and qualities of a king referred to simply as Chandra, who has been identified with the Gupta King Chandragupta II Vikramaditya (375-413). The inscription reads (in the translation given in the tablets erected by Pandit Banke Rai in 1903):
He, on whose arm fame was inscribed by the sword, when, in battle in the Vanga countries (Bengal), he kneaded (and turned) back with (his) breast the enemies who, uniting together, came against (him);-he, by whom, having crossed in warfare the seven mouths of the (river) Sindhu, the Vahlikas were conquered;-he, by the breezes of whose prowess the southern ocean is even still perfumed;-
(Line 3.)-He, the remnant of the great zeal of whose energy, which utterly destroyed (his) enemies, like (the remnant of the great glowing heat) of a burned-out fire in a great forest, even now leaves not the earth; though he, the king, as if wearied, has quit this earth, and has gone to the other world, moving in (bodily) from to the land (of paradise) won by (the merit of his) actions, (but) remaining on (this) earth by (the memory of his) fame;- (L. 5.)-By him, the king,-who attained sole supreme sovereignty in the world, acquired by his own arm and (enjoyed) for a very long time; (and) who, having the name of Chandra, carried a beauty of countenance like (the beauty of) the full-moon,-having in faith fixed his mind upon (the god) Vishnu, this lofty standard of the divine Vishnu was set up on the hill (called) Vishnupada.
It is believed by some that the pillar was installed in its current location by Vigraha Raja, the ruling Rajput Tomar king. One of the inscriptions on the iron pillar from A.D. 1052 mentions Rajput king Anangpal II.
