12 Interesting Facts about Iron Pillar of Delhi

The Iron Pillar of Delhi is an astonishing testament to ancient metallurgical expertise and engineering finesse. Situated in the Qutub Complex in Delhi, India, this remarkable artifact stands tall at around 23 feet (7 meters) high and weighs more than six tons. What sets this pillar apart is its remarkable resistance to corrosion despite being over 1,600 years old.

Crafted during the Gupta Empire, likely in the 4th century CE, this iron pillar is composed of 98% wrought iron and stands as a testament to the advanced knowledge of ancient Indian metallurgy. Its remarkable resistance to rust can be attributed to a thin layer of passive iron hydrogen phosphate hydrate forming a protective barrier, shielding it from corrosion through the centuries.

The inscriptions on the pillar, written in Sanskrit in Brahmi script, attribute its creation to King Chandragupta II, also known as Vikramaditya. The inscriptions praise the king’s achievements and military conquests. The pillar’s location near the Qutub Minar suggests that it might have been a part of a larger complex or a Vishnu temple, though there’s no conclusive evidence supporting this theory.

Scholars and scientists have marveled at the Iron Pillar for its exceptional corrosion resistance, with research conducted to understand the metallurgical techniques employed in its creation. It remains a symbol of India’s rich history and technological prowess, drawing visitors and researchers alike from around the world to witness this enduring marvel of ancient craftsmanship and scientific ingenuity.
