Rameshwar Mahadev Temple is located on Ram Gaya Ghat in Vindhyanchal approximately one kilometer from Vindyavasini Devi Temple and eight kilometers from Mirzapur. The temple derives its name from the puja or shradh performed by Lord Ram in reverence to Lord Shiva to propitiate his ancestors. It is believed that Lord Ram performed the ceremony on the directions of his guru Vashishta. He also installed a Shiv Ling in the shrine in their memory.
The temple is situated in the middle of two other temples dedicated to Vindhyavasini Devi and Ashbhuja Devi. The three temples together constitute what is called a Mahatrikone—the great triangle.
The devotees consider it an auspicious act to walk around the three temples as part of a ritual that is called Triloka Parikrama. According to folklore, Lord Ram also went to the temple of Goddess Vindhyavasini Devi to pay his homage after performing the shradhs or puja of the ancestors. Following the example of Ram, his brother Lakshman also established Laxmaneshwar Mahadev Temple which is situated close by.
