The building of the temple is after the Belur and Halabedu design with beautiful pillars.  There is a Lord Narasimha temple in the hill nearby and one for Lord Gopalakrishna on opposite side.

Majority of the devotees pray to Acharya Sri Ramanuja here for relief from the evil effects of spells and witchcrafts.

18 feet tall presiding deity Lord Perumal in the temple built by Acharya Sri Ramanuja appears majestically holding the conch in the right hand and the discus in the left.  The idol of Sri Ramanuja, as Adisesha is in the Lord Narasimha temple.  The Acharya also built a vast lake here which never goes dry.  The temple with its minute architecture and beauty is under the administration of the Department of Archeological Survey of India.

After leaving Srirangam in Tamilnadu, Sri Ramanuja sought asylum in this place.  He was received with all respects by one of his disciples Thondnur Nambi.  The place was then under the rule of one Pittidevan.  He was staunch Jain.  When Thaondanur Nambi visited him, he found the palace and all apartments plunged in darkness.  The king told Nambi that his daughter was possessed of a ghost and his Jain Gurus could not cure her.  Nambi assured the king that his Guru Ramanuja will drive the ghost holding his daughter.  The king was happy and promised that he would embrace Vaishnavism if the Guru saved the daughter.

Acharya Ramanuja came to the palace.  The king and the queen received him with all courtesy.  The Acharya spilled the water from his kamandala on the face of the princess.  She fell fainted but rose up with a clear face, completely free from the ghost effect.  Pittidevan and his wife became Ramanuja’s disciples.  Sri Ramanuja renamed the king Vishnuvardan.  Following the king, many shifted to Vaishnavism.

Acharya began his mission from this place to propagate his Visishtadvaita philosophy.  Vishnuvardan built many Vaishnava temples as desired by the Guru.  Temples for Belur Thalaikat Keerthi Narayana, Kodagu Veera Narayana and Melukot Seluva Narayana are a few among them, all speaking volumes of architectural beauty.

The Jains were not prepared to accept their defeat and alleged that Sri Ramanuja played some magic to cure the princess.  They challenged him for a debate which he accepted.  He faced 12,000 Jains from behind a curtain where Sri Ramanuja took the form of 12,000 hooded Adisesha and replied every objection raised by the Jains and defeated all the 12,000 Jains.
