Pazhaya Sreekanteswaram Temple or Old Sreekanteswaram Temple, located in Thiruvananthapuram, is one of the historic Shiva temples in Kerala. According to the famend historian Elamkulam Kunjan Pillai, this temple existed even within the ninth century AD. This temple is the original homestead of the Lord of new Sreekanteswaram Mahadeva Temple. The new temple is situated just outside the "North Fort" in Thiruvananthapuram. As cited through Dr. M. G. Sasibhooshan, the vintage temple became on the direction taken through the King of Travancore and his retinue in connection with the Pallivetta of the Sri Padmanabhaswamy Temple.
Lord Siva and Lord Krishna are the essential deities in Old Sreekanteswaram. The linga of Sreekanteswara is thought to had been mounted by Sree Parashurama. According to devotees, the samadhi of Sage Kanwa is inside the precincts of the Temple. Chettikulam, a pond close by that became reclaimed decades ago, is noted in Syanandura Purana Samuchaya and Anantapura Varnana as Kanvatirtha. This lends credence to the notion that Old Sreekanteswaram and Chettikulangara shaped a part of Kanwa Tapovana. The idol of Sri Krishna became hooked up later to lessen the ferocity of Shiva.
