Sri Bhaktavatsala Perumal Temple

As a Panchakanna Kshetram, this temple shares its grouping with Thirukkannapuram, Thirukkannankudi and two other Divya Desams associated with Krishna ("Kannan"), a set of five shrines scattered across the Kaveri delta that together form an unofficial Krishna-focused pilgrimage circuit for devotees who complete the main Divya Desam list. Thirukkannamangai is also unusual in housing a genuine image of the Buddha worshipped within the temple premises, alongside images of Vaikuntanatha and Vishnu mounted on Garuda, a rare and direct marker of the region's layered religious history, where Buddhist, Vaishnava and Saivite traditions once coexisted along the same stretch of the Kaveri delta.

The temple is also known locally as a Saptamrita Kshetram, "the place of seven auspicious elements," a traditional classification recognising the simultaneous presence at one site of a vimanam, mandapam, sacred grove (aaranyam), theertham, kshetram, river and town, a fuller set of ritually significant features than most Divya Desams claim together in one place.

Temple tradition and later inscriptional evidence together place the founding of this shrine in the late 9th century CE, under the Medieval Cholas, making it a comparatively early foundation among the Panchakanna group. Three separate Chola-period inscriptions survive at the site, and further contributions were made considerably later by the Thanjavur Nayaks, giving the temple a building history that spans several centuries of Tamil dynastic patronage.

The presence of the Buddha image within an active Vaishnava shrine is itself part of the temple's layered history, most likely reflecting a period when a Buddhist establishment existed in or near Thirukkannamangai before being absorbed into, or standing alongside, the growing Vaishnava temple complex, a pattern also seen at nearby Tirucherai.

The temple follows Dravidian architectural conventions, enclosed by rectangular walls with a rajagopuram rising to about 90 feet, modest by the standards of the larger Kaveri-delta Divya Desams, but a clear landmark within the village itself. The sanctum is crowned by the Utpala Vimanam, and the Saptamrita Kshetram classification is reflected physically in the temple's layout, which brings together its shrine buildings, sacred grove, tank and river frontage within a single compact site.

Daily worship follows the customary schedule of the Panchakanna Kshetrams.
