Later on, the Temple, which was under the Naduvil Madom Swamiyar, came in to the hands of the Mallissery Mana, situated near by.

It was in the year 1971 when the roof of the Sree kovil of this temple gave way due to dilapidation, that the remains, thereof, happened to be inspected by some local villager and devotees. During the excavation they formed this sacred Idol in act under the debris a long with the remains of Vathilmadom, Thidappally, (Kitchen) Chuttampalam (outer peripheral structure) outer wall and the Temple Tank. They took up on them selves, the Herculiyan task of resurrecting the Temple to its past glory and started renovation work in right earnest.
