over the sanctum. The history of the temple is unclear. In the early 18th century, King Vijayaraya Chakravarti II built the present day form of the temple. There is scant history of the period before that though it is believed that the locals worshipped the Goddess for many centuries before building the current temple. One legend says that the present deity was at the
Sri Ranganathaswamy Temple at
Srirangam, and one of the chief priests of the temple believed that the idol caused illness to
Ranganathar and hence asked it to be removed from the temple. It is a common belief in that part of the region that such local deities have immense powers and they must always be satisfied by proper offerings and sacrifices, otherwise, they cause epidemics. The idol was moved outside Srirangam and later found by some of the passersby who built a temple named, the
Kannanur Mariamman Temple. During that period (around the 17th century CE), Tiruchirapalli was ruled by the
Vijayanagara Empire kings and the area was used as an army base. It is believed that they made a commitment to build the temple if they win the war and after attaining success, they built a shrine for the Goddess.The Mariamman Urchavar idol was donated in the year 1991 by G.Balamurugan & G.Muralikumar, grand children of M.Venkatachala Padayachi & V.Valliammal & children of V.Gunasekaran & G.Kokila of No.1, Old Post Office Street, Ulundurpet, South Arcot Dist ==Architecture==
