Iron pillar of Delhi
A pillar of wrought iron about 7 metres tall and over six tonnes, now standing in the Qutb complex in Delhi. Its Sanskrit inscription praises a king Chandra, identified as Chandragupta II of the Gupta Empire, and calls it a standard of the god Vishnu.
It probably first stood elsewhere, perhaps at Udayagiri, and was moved to Delhi in the 11th century. It has barely rusted in 1,600 years because of a thin protective layer formed on its high-phosphorus iron.
