Sowmya Narayana Perumal Temple stands in Thirukkoshtiyur, Tamil Nadu, is dedicated to Sowmyanarayana Perumal (Vishnu) with consort Thirumaamagal Thayar. It is also known as Thirukoshtiyur Perumal Temple, Sowmiya Narayana Perumal Koil.
Sowmya Narayana Perumal Temple is one of the 108 Divya Desams, the Vishnu temples glorified in the Naalayira Divya Prabandham composed by the Alvar poet-saints. Beyond its Divya Desam status, it holds special importance in Sri Vaishnava tradition as the site associated with Ramanuja's guru Thirukoshtiyur Nambi and the public proclamation of the Ashtakshara mantra, an episode widely cited in Sri Vaishnava teaching about compassion overriding secrecy. Thirukkoshtiyur is one of the oldest sites among the Divya Desams, with shrines to Narasimha and other forms of Vishnu alongside the main sanctum.
Tamil Nadu carries a distinct temple identity of its own: Land of towering gopurams and living Dravidian temple traditions, from the Chola masterpieces to the great Pancha Bhoota Sthalas.

History and architecture
Architecture
Dravidian style temple on about 2 acres, with a five tiered raja gopuram and rectangular granite enclosure walls. Its Ashtanga Vimana rises about 25 meters, taller than the gopuram, an unusual feature found in only two other temples, Uthiramerur and Cheranmadevi (Koodal Azhagar in Madurai also has a distinctive Ashtanga Vimanam)
History
Thirukkoshtiyur is one of the oldest sites among the Divya Desams, with shrines to Narasimha and other forms of Vishnu alongside the main sanctum. The temple is glorified in the Naalayira Divya Prabandham by Alvars including Periyalvar, Thirumalisai Alvar, Bhoothathalvar and Peyalvar. It is most famous in Sri Vaishnava tradition as the place where Ramanuja's guru, Thirukoshtiyur Nambi, taught him the sacred Ashtakshara mantra (Om Namo Narayanaya) only after Ramanuja made repeated visits, traditionally said to number eighteen. Nambi initially instructed that the mantra be kept secret, warning that revealing it improperly would lead to hell. Moved by compassion for ordinary people, Ramanuja is said to have climbed the temple tower and proclaimed the mantra publicly to the gathered crowd, saying he was willing to bear the consequence alone if it meant many would attain liberation. Rather than being angry, Nambi is said to have approved of the act and given Ramanuja the honorific title Emperumanar. A life sized statue of Ramanuja stands in the temple's Ashtanga Mandapam commemorating the episode.
