Hindu Temples Harihar Nath Temple, Sonepur
A rare temple where Hari (Vishnu) and Hara (Shiva) are worshipped together in a single Shivalinga — half Shiva, half Vishnu. Set near the sacred confluence of the Gandak and Ganga, it is traditionally believed to have been founded by Lord Rama on his way to Sita's swayamvar. Every year it anchors the famous Sonepur Mela, once among Asia's largest cattle and elephant fairs.
