As per history, the ancient temple was destroyed by Tipu Sultan. The Hindus of the region especially Brahmins were killed and the temple remained in a dilapidated condition for several years. Kalliat Thazhath Veettil family later acquired the temple. The family was worshippers of Devi and this led to the development of the temple.
In a Devaprasnam held here it was revealed that Mamanikkunnu Sri Mahadevi wanted her to be worshipped in Saktheya method. The pujaris were performing Sattvik puja. The aradhna and puja were changed to Saktheya system. Special priests from Pidarar (Moosad) community were invited and settled in the surrounding of the temple for the purpose.
