Thirumanikkoodam or Varadaraja Perumal Temple is located in Thirunangur, a village in the outskirts of Sirkaḻi in the South Indian state of Tamil Nadu.

Constructed in the Dravidian style of architecture, the temple is glorified in the Nalayira Divya Prabandham, the early medieval Tamil canon of the Alvar saints from the 6th–9th centuries CE.

As per legend, the Hindu god Shiva started dancing in fury at this place after the death of his consort Uma due to the yajna (sacrifice) of Daksha.

It is located close to Thirunangur, a small village, 8 km east of Sirkali en route to Thiruvenkadu.

During the worship, religious instructions in the Vedas (sacred text) are recited by priests, and worshippers prostrate themselves in front of the temple mast.

During the new moon day of the Tamil month Thai, the festival deity of Thirumangai Alvar is brought to the temple from Thiruvali-Thirunagari.

The festive image of Thirumangai Alvar is also brought on a Hamsa Vahanam (palanquin) and his paasurams (verses) dedicated to each of these eleven temples are recited during the occasion.

During the 18th and 19th centuries, the temple finds mention in several works like 108 Tirupati Antati by Divya Kavi Pillai Perumal Aiyangar.

As per local belief, the fresh winds which swirl the paddy fields before the day of the festival indicates a good harvest for the season.
