According to Shiva Purana, there are nine Avatars (incarnation) of Lord Shiva. Barabar Hill is believed to be abode of one of these Avatars of Lord Shiva. There is a great faith and belief in Siddheshwar Nath (Lard Shiva) in local population. Local people of Jehanabad, Gaya, Vaishali, Nawada, Rohlas and other districts of Bihar and nearby districts of UP consider Siddheshwar Nath as God of Gods (Nathon Ke Nath) and believe that Lord Shiva resides in Barabar Hill and if one prays with devotion and pure heart then Baba Siddheshwar Nath fullfil his or her wishes. Devotees find Lord Shive here in the form of Shivalingam. Local youth come here in Shravan manth (15th July to 15th August), called Kanwarias, with their Ganga Jal (water) pot to offer to Shivalingam. 

According to sign board installed at Barabar Temple Gate this temple was probably constructed in 7th Century AD. There is also a statue of Maa Durga (Mother Goddess Shakti) installed in the temple. According to inscription on this statue, construction of this temple was started in Gupta period. According to myths in local population, construction of this temple was done by King Vana, who was father in law of King Jarasandh of Mahabharata period. Local population also believe that legend Ashwatthama of Mahabharata period got fame by praying 19 prayers of Lord Shiva and he got penance from his evil deeds. He got blessings of Lord Shiva and resided in the Barabar Hill.
