Sri Sowriraja Perumal Temple

Thirukkannapuram is counted as one of the five Pancharanga Kshetrams and, among the five Panchakanna (Krishnaranya) Kshetrams associated with Krishna along the Kaveri delta, is traditionally regarded as the foremost of the group, giving this coastal shrine a standing among Krishna-linked Divya Desams beyond what its relatively modest size might suggest. The deity is worshipped here under two names, Sowriraja Perumal and Neelamegha Perumal ("the lord of the dark rain-cloud hue"), both referring to the same sanctum image.

Five Alvars (Thirumangai Alvar, Periyalvar, Andal, Kulasekara Alvar and Nammalvar) are credited with singing mangalasasanam here, a substantial number of Alvar attributions that places Thirukkannapuram among the more frequently celebrated Divya Desams in the Naalayira Divya Prabandham, despite its relatively remote coastal location near Nagapattinam.

The temple's best-known legend concerns why the deity is called Sowriraja Perumal, "the lord who wore a wig." Temple tradition holds that Rangabhatta, a devoted priest at the temple, received a garland each day from a courtesan to offer to the deity, a garland that she had first worn herself before passing it on. When the local king one day discovered a strand of hair caught in the garland and confronted the priest over the impropriety, the priest defended himself by insisting the hair belonged to the deity, not the courtesan. To vindicate his devotee before the king, Vishnu is said to have appeared wearing a sowri, a wig of flowing hair, proving the priest's claim true, and giving the deity the name Sowriraja Perumal ever since.

Beyond the legend, the temple's foundation and standing among the Panchakanna group place it firmly within the broader wave of Chola-era Vaishnava temple-building along the Kaveri delta and its coastal approaches near Nagapattinam, a period that also produced most of the neighbouring Divya Desams in this stretch of Tamil Nadu.

The temple follows the typical Chola-period Vishnu temple layout of the region, with a sanctum crowned by the Uthbalavadaka Vimanam housing Sowriraja Perumal, and a separate shrine for Thayar, worshipped here as Kannapura Nayaki. As with most Divya Desams along this coastal stretch, the layout reflects Dravidian conventions rather than any single monumental architectural showpiece, with the temple's devotional and legendary associations carrying more of its distinct identity than its scale.

Vaikunta Ekadashi and the temple's annual Brahmotsavam are the principal festival occasions observed here, drawing devotees from across the Nagapattinam district and beyond, particularly given the temple's standing as the foremost of the five Panchakanna Kshetrams.

Daily rituals follow the customary schedule of the Nagapattinam-district Divya Desams.
