Iron pillar of Delhi

The Iron Pillar of Delhi rises 7.3 meters high with a diameter of 41 centimeters and weighs over 6 tons in the Qutb Minar complex.

The Sanskrit inscriptions on the pillar date from the 4th century CE and document the victories of King Chandra, identified as Chandragupta II of the Gupta Empire.

The pillar features ornate carvings and stands within the first mosque built in Northern India, reflecting the intersection of Hindu and Islamic architectural elements.

Visitors can observe the pillar's protective layer, which scientists have identified as crystalline iron hydrogen phosphate hydrate, preventing corrosion for over 1,600 years.

The metallurgical composition includes 0.25% phosphorus and 0.15% carbon, created through forge welding of multiple iron lumps weighing between 18 to 23 kilograms each.
