About:

This temple is dedicated to Hindu god Vishnu. This temple is constructed in Dravidian style of architecture. The temple has two inscriptions dating from the Chola period. The temple has a five-tiered rajagopuram (gateway tower) and enshrined within a granite wall. The complex contains all the shrines and water bodies associated with it.

Structure:

It is named as Suddhananda, meaning “pure happiness” . Devotees who worship this vimana(tower) derive immence and unalloyed happiness. Note that the vimana in Tirumala Tirupati is named as Ananda vimana, whereas here it is Suddhananda Vimana.

Desika’s sannidhi is located near the sancturn sanctorum. On the sides of the inner-prakara (Corridor), Anjaneya is on the south, and Alwars’ and Sri Rama’s sannidhis are located on the northern side. On the eastern side is Sri Ramanuja.
Outside the main temple, on the southern side is the shrine for Lord Maniappan and on the northern side is Ennappan and also the holy birth spot (avatara sthala) of Bhoomidevi. Garuda’s shrine is located right opposite the main temple. Just on the southern side of the main entrance, dancing Krishna in a niche welcomes us all with a bewitching smile.

There is a small garden by the side of the outer prakara of the temple. There is also a much bigger garden about 1/2 km to the south of the temple, where tulasi and flowers are grown in abundance for weaving garlands daily for the deities. A big mandapa is located in this garden, where deities rest during the day in summer, during the Vasantotsavam celebrated for 6 days in May-June every year.

Lore:

There is also a story behind the tank in this temple. Once a King had consummated with a daughter of a saint and hence the saint cursed him to become a bird. The king lived as a bird and one night when there was a storm and the branch of the tree the bird was sleeping on broke and fell into the water of this tank. The bird which got dipped by this accident in the tank regained its original form as the King and since then this is known as the only theerththam that one can do theerth thaadanam even in the night. Since this tank has such a healing power in the day as well as night, it is called “Ahoraathra Pushkarani”. The place is referred by various names like “Agasa Nagaram”, “Vaikunda Nagaram”, “Thiruvinnagar”, “Oppiliappan Sannithi” and “Uppiliappan Sannithi”. The presiding deity is referred by various names like Venkatachalapathy, Thiruvinnagarappan, Oppilaappan, Thanoppillaappan, Uppiliappan and Srinivasan.

The chariot festival, celebrated during the Tamil month of Chittirai (March–April), is the most prominent festival of the temple. The temple is maintained and administered by the Hindu Religious and Endowment Board of the Tamilnadu Government
