Scientists still argue about the purpose of this column in Delhi. The monument is located 20 km south of Delhi itself, although it is believed that the column was installed in this place only in 1050. Its height is 7 m. Weight is 6.5 tons. Age 1600 years. The most amazing thing is that during all this time the column was not covered with rust.
Scientists repeatedly took metal samples for study and each time the results of the analyzes baffled them. There are practically no impurities in the material, i.e. this metal is essentially 100% iron, with no manganese, no nickel or any additives that can resist corrosion.
What is the secret of the mysterious artifact? What recipe for iron was known to the ancient Hindus? Who gave them this knowledge?
It is called the Eighth Wonder of the World. The iron column in the courtyard of Qutb Minar, like a magnet, attracts not only tourists, but also researchers as a magnet. However, scientists have not yet been able to answer one important question: who and why built this strange structure?
Samples of the mysterious metal have been sent to several different laboratories around the world. The results of the physico-chemical composition were shocking. It turned out that the column was made of the purest iron. How did the ancient Indians manage to get the metal without any impurities? But the main question is, how did they make the iron not rust, because this is contrary to all the laws of nature?
Scientists argue that today, not every steel plant is capable of smelting such a large piece of iron. How, then, did the ancient people manage to produce a pillar as high as a two-story house and as thick as a tree?
The researchers failed to find a single trace of forging, only one inscription in Sanskrit dedicated to the ruler of India Chandragupta II (scientists believe that it was made much later than the column itself).

It turns out that the ancient Indians possessed such knowledge in metal processing, which we in the 21st century do not even suspect. Who taught them these technologies?
Scientists failed to reveal all the secrets of the Qutub column. However, most of them agreed that this mysterious pillar could be a kind of radio tower or antenna. If aliens are guided by it in order to get to us on Earth, then maybe the column will show us in which direction to look for another inhabited planet?
