The cult of Saivism has found expression in Bihar in a large number of Shiva temples and particularly on the districts bordering Nepal. North Bihar districts, namely, Champaran, Saran, Muzaffarpur, Darbhanga and Saharsa have got quite a few Shiva temples.

The influence of Nepal, where Saivism has a very great holds, is clearly one of the reason why there are so many Shiva temples in these boarder districts. Many of these Shiva temples are visited by thousands of pilgrims from Nepal.

The Singheshwar temple at the village Singheshwar in Saharsa district is one of the ancient Shiva temples in Bihar. It is visited by lakhs of pilgrims in the course of a year although it is not very easily accessible from the other parts of Bihar.
