Sri Sri Harisankar Devasthana, is a temple on the slopes of Gandhamardhan hills, Odisha in India. It is popular for its scenes of nature and connection to two Hindu lords, Vishnu and Shiva. As a holy place, along with a stream passing on the granite bed, it has given some visitors a feeling of peace. On the opposite of side of the Gandhamardhan hills is the temple of Nrusinghanath. The plateau between the two temples has been found to have ancient Buddhist ruins, which are considered to be remnants of the ancient Parimalgiri University.
The deity of Harisankar was discovered by a Chauhan dynasty king of Patna kingdom of Odisha, during the 14th century. From that time, the deity has been worshipped. A dancing Ganesha image has been found, which can be traced to the early 12th century. The temple was constructed by the order of then queen Durlabha Devi of Maharaja Vaijjal Dev Chauhan.
