The iron pillar (also known as the Ashokan pillar) of Delhi, India, is a 7 m (23 ft) high pillar in the Qutb complex, notable for the composition of the metals used in its construction. The pillar, which weighs more than six tons, is said to have been fashioned at the time of Chandragupta Vikramaditya (375–413) of the Gupta Empire, though other authorities give dates as early as 912 BCE.
