Singheswar Sthan Mandir is one of the historical shrines of Madhepura that is of religious importance. This temple is dedicated to Lord Shiva. It is being opined that at the time of Ramayana period Putreshthi Yajna (Sacrificial ceremony for a son's birth) was performed by Raja Dashratha, who was blessed with four sons’ from the Prasad “Charu” of that mahayagya. The mighty Sringhi Rishi chiefly prayed for Lord Shiva on the occasion of that Yagya. Seven “Havana Kunds” were created during that time, which have been converted into a dilapidated tank now. Also, the residential place of Sringi Rishi became famous as Singheshwar with the passage of time.
Singheshwar Sthan is also a popular pilgrimage centre of Lord Mahadeo in the country. It is located at a distance of 8 km from Madhepura Dist. H.Q. and is famous for its historical and religious importance. Maa Bhavani is known as Singheshwari and Lord Shiva is known as Singheshwar here and worshippers not only from Bihar but also from various locations of the country apart from the neighboring country Nepal visit Singheshwar Sthan for offering prayers to Lord Shiva. Certain days of the week like Sunday, Monday & Wednesday are much crucial for the devotees to perform special pujas. Mahashivratri mela of Singheshwar Sthan is popular in Bihar and Trai region of Nepal as well.
There are several myths associated with the importance of this religious place that was once a tapobhoomi of the great sringi Rishi. This shrine has been popular during the emergence of idol worship in the pauranic times. Pandit Jharkhandi Jha in “Bhagalpur Darpan” has spread the religious importance of this place. References of Singheshwar Sthan can be observed in Bramha puran too. As per the puran, this place was occupied with dense forests. Cattle rearers used to visit this place during which the grazing of one virgin cow used to sprinkle milk from her breast on a specific location. They viewed the charismatic act of that cow one day and began to explore that place. After digging, they got a shivalinga there and began to worship. Slowly, people became wary of this event and in course of time a small temple was built there with the contribution of the devotees. Another reference of Bramha puran is also quoted here. Once Vishnu, Brahma and Indra went to Kailashpuri to discuss some crucial aspect of global events. However, Lord Shiva was not present there. They looked form intensely but returned hopelessly. During their return journey, telepathy indicated them that Lord Shiva in the guise of a deer is living in a secluded place of the deep forest. The omniscient Lord located the unique dear decorated with unparalleled beater in the guise of Lord Shiva and took control of him after strong attempt. The Tridevs hold the horn (sing) of the deer in three places. Lord Indra managed the upper portion, Lord Brahma the middle and Lord Vishnu the lower portion of that horn. Abruptly, it broke into three parts. They got one-third part of that horn and Lord Shiva disappeared. Later, a forecast was heard that Lord Shiva will not be visible then. Eventually, Tridevs had to be content with that very part of the horn. It is observed that Lord Indra established that horn in the heaven, Lord Brahma in the same place and Lord Vishnu seremonized his part in Singheshwar for the wellbeing of humans. Due to this event, Lord Shiva is worshipped by Vaishnav Cult here. The author of “History of Baba Mahathya of Singheshwar Sthan” mentioned the historical and religious aspects of Shiva Temple at Singheshwar Sthan.
