It is believed that this particular campus once had 27 Hindu and Jain temples. The exquisite carvings and pillars seen on some of the ruins shows the legacy of the bygone era. This complex is believed to be a centre of worship for Hindus before the Muslim invasion in India.
One more wonder inside the premises is the Iron Pillar which, over the years has not corroded. R Balasubramanium from IIT Kanpur explains that the pillar's resistance to corrosion is due to a passive protective film at the iron-rust interface. It is believed to be a perfect example of metallurgy and makes one wonder as how people used to forge and do metal casting in those times without the use of modern technology. The iron pillar bears an inscription in Sanskrit and has the name 'Chandra' inscribed in it. This pillar is believed to be initially present in Udayagiri in Madhya Pradesh. This is one of the masterpieces India has produced.
