More than the Ghats and even the Ganga, the Shivalingam installed in the temple remains the devotional focus of Varanasi . Varanasi is said to be the point at which the first jyotirlinga, the fiery pillar of light by which Shiva manifested his supremacy over other gods, broke through the earth’s crust and flared towards the heavens.
The original temple was destroyed by Aurangzeb who built a mosque in its place, but the traces of the old temple can be seen behind the mosque. The present temple was built by Maharani Ahilya Bai of Indore in the year 1776 and the gold plating on the towers of the temple was provided by Maharaja Ranjit Singh of Indore .
To the side of the temple is Gyan-Kupor (‘the well of Knowledge'). It is believed that the Shiva Lingam removed from the original temple was hidden in this well to protect it from Aurangazeb and it still lies there. Non-Hindus are not allowed to enter the temple.
New Vishwanath Temple : This temple is situated in the premises of the university and has 'Geeta' engraved in its marble walls.
