Sarkaradevi Temple is one of the most important temples in South India. It is situated South of the Chirayinkeezhu Taluk (in the North-West of Thiruvananthapuram district.) Tradition accords a remote antiquity to this temple. Its main deity is Bhadrakali. The sarkaradevi Temple assumed a significant status many reasons and rose to historical importance mainly with the introduction of the famous Kaliyoot festival by Anizham Thirunal Marthanda Varma, the Travancore sovereign, in 1748.
Chirayinkeezhu Taluk being directly under the immediate administration of the Attingal Swarupam, the Attingal Ranis where entrusted by the Travancore Raja with the conduct of the elaborate festival of Kaliyoot. The Attingal Rani being related to the Travancore royal family through adoption from the Kolathunad royal family. From the time of Venad Kings, had enjoyed independent rights in several respects over the neighbouring regions and temples and at times even over the entire Venad. Even the King Marthanda Varma annexed Attingal to Travancore,soon after ascending the throne Marthanda Varma decided to assume direct control over Attingal 'estate'. The Ranis seem to have been allowed to continue in their independent status in many respects. Hence it was no wonder that when the former decided to introduce Kaliyoot festival in the Sarkaradevi Temple of Chirayinkeezhu Division, he entrusted the responsibility to the Attingal Ranis, even though the finances came directly from the Travancore royal treasury.
The Attingal Ranis in the turn bestowed the members of the military family of Ponnora Panickers (When two princesses were adopted from Kolathunad, some senior members of the Ponnara family are said to have accompanied them as bodyguards to Attingal, where the former were settled by the Venad Kings. The descendents of the family are still residing there, with the responsibility of supervising the grand festival. Even now the responsibility is continuing with the descendents of the Ponnara family. One of the most important peculiarities of this temple is that it is the only temple in South Kerala where such elaborate Kaliyoot festival is conducted. Another festival which makes the temple the center of attraction is the Meenabharani mahotswavam which is conducted for ten days in the month of March-April every year.
