The Ular Surya Temple, located in the Dulhin Bazaar area of Patna, organizes a grand fair on the occasion of Chhath. The history of this temple is associated with the Dwapara Yuga, where Maharaja Shambh, the son of Lord Krishna, built it to cure leprosy. It is believed that there are 11 Surya temples in India and one in Pakistan, all built by Maharaja Shambh in the Dwapara Yuga. The evidence of the construction of the Surya temple in 12 different places based on the 12 zodiac signs is mentioned in the Shambh Puran.
