As I m a citizen of Varanasi I suggest if you coming to Varanasi must visit famous place Shri Kashi Vishwanath Mandir which is in BHU.

Shri Kashi Vishwanath Mandir is one of the famous temples of Varanasi. Kashi Vishwanath Mandir was destroyed many times but in 1930 Pandit Madan Mohan Malaviya decided to replicate Shri Kashi Vishwanath Mandir temple in the campus of Benaras Hindu University. The temple was finally completed in 1966. It took 35 years to complete(1931-1966).

Thank you.
