The iron pillar located at Mehrauli village on the outskirts of Delhi has fascinated scientists and ordinary people for centuries. Scholars consider the pillar to be from the early Gupta period. It is a wonder that such a huge metallic object could be fashioned so many centuries ago.
However, most amazing is the fact that it has not rusted at all, despite being exposed to the sun, rain, and wind through all these ages. Chemical analyses have indicated that the pillar was astonishingly pure or low in carbon compared with modern commercial iron, and historians have termed it ‘The Rustless Wonder’.
