The temple region is situated on the north of the holy Pampa River of Kerala.  This is mentioned in the hymns of Nammazhwar.  Of the temples installed by Pandavas, this is the temple that celebrates more festival events.

Perumal grants every wish of the devotee.

While digging the land in this place, new Perumal-Vishnu idols were found.  They were brought to this temple and new shrines built to install the new idols.  It is significant that the sanctum sanctorum is circular in shape and Perumal in a standing form is facing west hold his conch and discus.  The sculpture depicting the dance of Child Krishna on the hoods of snake Kalinga (Kalinga Nardanam) is very attractive.  The two pillars bearing this Naradana Kanna has also carvings of all Dasavatara (10 incarnations of Lord Vishnu) scenes.  The Vimana – tower above the sanctum sanctorum is called Sakala Veda Vimanam.  Maharshis Narada and Markandeya had visited the temple to worship Perumal Pamabanaiappan.

A debate arose between Lord Brahmma and Maharshi Narada.  Brahmma spelt a curse on Narada who came down to this place and performed penance on Lord Vishnu seeking his grace to teach him all the philosophies covering creation and related principles.  Pleased with his penance, Lord taught him the lessons based on which Maharshi Narada wrote the treatise on the supremacy of Lord Vishnu and the codes to worship Him, titled Naradeeya Puranam, according to scriptures.
