The Goddess is seated in a separate shrine in the Alankaravallithayar temple. It can be known through the inscriptions that kings such as Kulothungan II, Rajarajan II, Kulothungan III, Rajarajan III, Sadayavarma Kulasekaran, Tippayya Devamakarayar, etc. were involved in the restoration of this temple.

The internal and external structures of the temple, the gate, and all the structures have been accurately measured and recorded in the field survey.
