"The Iron Pillar of Delhi: A Monument to Ancient Indian Engineering"

 Located in the Qutub Complex in Mehrauli, Delhi, the Iron Pillar is a fascinating ancient structure. Standing for over 1600 years, this pillar is known for one amazing fact – it hasn’t rusted much over time. This shows how advanced India’s engineering was in the old days.


The pillar is around 7.2 meters high and weighs more than 6 tons. Experts believe it was built during the reign of King Chandragupta II in the 4th century CE. An inscription in Sanskrit carved on it praises the king and tells a bit about the history of that time.


What surprises many people is how the iron has stayed almost rust-free. Usually, iron gets rusty when it faces wind and rain, but this pillar has not. Scientists think that the craftsmen of that time used a smart method to mix the iron with phosphorus and did not use materials like sulfur, which causes rust. This clever process helped protect the pillar for centuries.


The Iron Pillar proves that ancient Indian metalworkers had great knowledge of chemistry and metal science. It is not just a historical object, but also a reminder of India’s genius in science and technology long ago.


Visitors from all over the world come to see this marvel and admire the skills of ancient Indian craftsmen.
