Gangesvara Siva Temple is situated within a precinct on the left side of Ganga-Yamuna road(leading from Talabazar Chowk to Ganga-Yamuna temple) Old Town, Bhubaneswar
. It is located at a distance of 200 metres north-east of Lingaraj temple, 50 metres north of Lakhesvara temple across the road, 200 metres south of Subarnesvara and 100 metres east of Gourisankar temple. The temple is facing towards east. The presiding deity is a Siva lingam within a circular yonipitha. It is a living temple and maintained by the Ganga Yamuna Sangathana.
There is a common belief among the local people that Goddess Parvati killed the demons Kirti and Basa in the Ekamra Kshetra. After this heroic incident, the deity felt thirsty. In order to quench the thirst, Lord Shiva struck his trident into the earth. A spring came out and to consecrate the spring river goddess Ganga and Yamuna were invited. To commemorate the incident twin temples of Gangesvara and Yamunesvara were constructed during the Ganga rule in Orissa
. However, the present monument is a later renovation over the original shrine as evident from the use of earlier building materials used in a non-schematic manner and depiction of sculptures of later period in the jangha.
The temple is carved with secular images on both the janghas. In the western wall, tala jangha portion there is a female figure holding a child in her both hands. The female wears a manibandha, beaded necklace and armlet with bulbing hair. The upara jangha, bears a nayika in standing pose pushing something into her genital organ in her left hand while her right hand is resting on the ground. In the kanika paga, the tala jangha has a darpana image and the upara jangha sculpture has a male figure holding a rectangular flat shaped object on his left hand and the right hand resting over the right knee. In the right side of the raha paga, the lower jangha is carved with a male warrior who holds a sword in his right hand and a shield in left hand. In the upara jangha, there is a woman in yonibhiseka pose standing over a fire pot with splayed out legs, the figure either urinating or taking the warmth of the fire. Her right arm is in abhaya mudra and the left arm resting over her left knee.
