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.

The Thirumangai Alvar Mangalasasana Utsavam celebrated annually during the Tamil month of Thai is the major festival of the temple during which the festival images of the eleven Thirunangur Tirupatis are brought on mount designed like Garuda, called Garuda Vahana, to Thirunangur.

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.

There is a hall adjacent to the right of the rajagopuram, where the festival image of the fourteen temples in Thirunangur and its surrounds are housed during the Thirumangai Alvar Utsavam.

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

[6] It is believed that saint Thirumanagai Alvar visits the place every year to the festival to consecrate the eleven deities.

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

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

[6] 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 pasurams (verses) dedicated to each of these eleven temples are recited during the occasion.
