The Iron Pillar located in Delhi, India, is a 7 m (23 ft) column in the Qutub complex, notable for the rust-resistant composition of the metals used in its construction. Some authors attempted to identify Candra with Chandragupta Maurya and yet others have claimed the pillar dates as early as 912 BCE.

The height of the pillar, from the top of its capital to the bottom of its base, is 23 ft 8 in (7.21 m), 3 ft 8 in (1.12 m) of which is below ground. Its bell pattern capital is 3 ft 6 in (1.07 m) in height, and its bulb-shaped base is 2 ft 4 in (0.71 m) high. The base rests on a grid of iron bars soldered with lead into the upper layer of the dressed stone pavement. The pillar's lower diameter is 16.4 in (420 mm), and its upper diameter 12.05 in (306 mm). It is estimated to weigh more than six tons

The pillar has attracted the attention of archaeologists and metallurgists and has been called "a testament to the skill of ancient Indian blacksmiths" because of its high resistance to corrosion. The corrosion resistance results from an even layer of crystalline iron hydrogen phosphate forming on the high phosphorus content iron, which serves to protect it, and also the effects of the local Delhi climate, which alternates from wet to dry.
