The Hindu writes about the temple
The penance began and pleased with their dedication, Narasimha emerged in a ferocious form. The place is Keezhapavur where in the temple the deity is seen with 16 hands, Hiranyakasipu on his lap. He is called Ugra Narasimha and Prahladavaradar. At the deity’s feet in total surrender are Kadamba Maharishi, Prahlada, his mother Lilavati and the king of Kasi.
To cool the angry Narasimha appeared a pond, aptly called Narasimha Theertham. There is a shrine for Sri Prasanna Venkatachalapathy with his Consorts Padmavati and Alarmelmangai. There is no statue of the latter.
Location - Pavurchatiram, also known as Pandiya Ahobilam, is 37 km from Tirunelveli and 16 km from Tenkasi. Keezhapavur is located 2 km from Pavurchatiram, on way to Karandai. The temple is close to the bus stand.
How to go: All buses on the Tirunelveli-Tenkasi route pass Pavurchatiram, where pilgrims should alight and board a bus to Keezhapavur. Or take autorickshaws.
