Thousand years ago, a childless Pallava King Jambu was on a pilgrimage tour. On his way, the axle of his chariot broke at sembakkam and he was resting. In his deep sleep, Lord Shiva appeared in his dreams and directed him to construct a Shiva temple by name Jambugeswarar at sembakkam, so that he would take abode along with Goddess Azhagambigai and give blessings to the devotees and the King would soon have a child. The King obeyed the request of Lord Shiva and built the Lord Jambugeswarar temple. He was fortune to have a child as blessed by Lord Jambugeswarar. The Temple was also said to have been built by Chola King Koch Sengannan and later renovated by Chola Queen Sembian Madeviyar and got the blessings of the God.
According to the blessings given by His Holiness Sri Kanchi Kamakoti Peetadhipathi Jagadguru Sri Chandrasekara Sankaracharya Swamigal, Kancheepuram ( “Periyaval”), this temple is in existence from time immemorial, since there are vast references about this temple in other ancient legends (puranas) like Machapuranam, Koormapuranam, Vamanapuranam, Pavushiyapuranam, Lingapuranam etc., The ancient character of Sembakkam justifies the presence of so many important temples and temple tanks in and around Sembakkam. Seervalarseer Arul kaviarasar Devikarumaridasa Swamigal, author of Thiruverkadu Karumaripuranam and Adeenakarthar of Arulmigu Jambugeswarar Iraipani Mandram has planned to write regular Uthara Jambugeswarar Sthalapuranam in 5555 songs with 32 Padalam (Chapters) based on the information available in the ancient legend like Machapuranam, Koormapuranam, Vamanapuranam, Pavushiyapuranam, Lingapuranam etc.,
