Sri Vaigunta Nathan Perumal Temple Nagapattinam
The legend of all the eleven temples of Thirunangur is closely associated with each other. As per legend, the Hindu god Shiva started dancing in fury at this place after the death of his consort Uma due to the yagna of Daksha. Each time his lock of hair touched the ground, there were eleven other forms of Shiva who appeared. The celestial deities were worried that if the dance continues, it would result in the decimation of entire creations. They prayed to Vishnu for help, who appeared at this place. On seeing Vishnu, Shiva's anger was reduced and he requested Vishnu to appear in eleven forms like he did. On his request, Vishnu appeared in eleven different forms at Tirunangur. The eleven places where Vishnu appeared are believed to be where the eleven temples in Tirunangur are located
