This hill also has a lot of historic importance as it was once a seat of Buddhist culture. To date many ruins are found on the plateau at the hilltop. According to Hindu theology, Lord Hanuman carried this hill on his shoulders from Himalayas to save the life of Lakshman. In the Tretaya Yug (the Silver Age), Sushena (the expert physician in the Vanara Sena that followed Ram) had suggested Vir Hanuman to bring Bisalyakarani ere dawn, so that Laxman would rise back to life. It was in the middle of the war between Lord Ram and Ravan. Hanuman failed to identify the particular herb and carried on his shoulders a huge Himalayan mass. While flying above and proceeding toward Lanka (the kingdom of Ravan), a portion dropped down. Gandhamardan is synonymous to that portion only. At the northern slope of this hill the Nrusinghanath Temple is located; whereas on the southern slope of this hill is the famous Harishankar Temple.
