The place where the Chengannur temple is situated was said to be under the control of Vanghipuzha Thampuran.
Vanghipuzha Thampuran on the advice of Thazhaman Potty showered 36 para (measurement in Malayalam) of Neyy (Ghee) on that stone in order to stop the blood.
The Thampuran in consultation with Thazhaman Potty and other veteran Brahmins decided to construct a temple there. Based on the plan of Perunthachan, a famous and respected Thachan (carpenter), the temple except the kuthambalam was constructed. Though the temple was constructed in accordance with the plan of Perunthachan, the kuthambalam could not be constructed by any of them. The whole kuthambalam was constructed under the guidance of Perunthachan. The structure of the Kuthambalam originally constructed by Perunthachan was in such a manner that the shadow of the performer would not fall on the stage if all the lamps were lit on each of the post of the kuthambalam.
On completion of the construction of temple and kuthambalam the Thampuran requested Perunthachan to make an idol of Devi. He pointed out a place and asked the workers to dig that place. On digging an idol of Parvathi Devi was found and this idol has investiture at the nearest auspicious occasion.
After some years Perunthachan Visited the place again and informed Thazhaman Potty that the temple would be destroyed in fire in due course and Idol of Devi would be destroyed. He also gave an Idol of Devi made up of an alloy of five metals ( Panchaloham ) and asked him to keep a record of what he said. The Potty did accordingly. After some years the prediction of Perunthachan become true.
The temple was renovated after the fire and Devi's Idol had been taken from the river with the help of some fishermen (Arayas) of Karunagappalli, as recorded in the Grandha written by Thazhaman Potty. As a mark of joy thampuran gave fruits and tender coconuts to those arayas at the temple. This happened on a Shivarathri and now also this day is celebrated with the same tradition.
