Thirumukkoodal has an ancient temple for Lord Vishnu called ‘Sri Appan Prasanna Venkatesa Perumal’.
On hearing this Thondaiman prayed to Lord Venkatesa Perumal and the Lord blessed him to win the battle and gifted him with His Sanku (Conch) and Chakra (Wheel). Thondaiman successfully won the battle and on his way back both the weapons Sanku and Chakra vanished. Later, the Lord directed Sri Ramanujar to install Sanku & Chakra for Him at this place. That’s how the deity here had got Sanku & Chakra here.
The Lord here is said to have given dharshan to Brigu Maharishi, Markandeya and Bhumadevi (mother Earth).
There are 3 Sthala Virukshams (holy trees) for this temple, which are Devadhaari, Vanni and Sandhanam (Sandal).
The Thaayaar (Goddess) here is Sri Alarmel Mangai Thaayaar for whom there is a separate shrine present at the temple.
Other deities like Sri Varadhar, Sri Aandaal and Sri Anjaneyar (Hanuman) have separate shrines in the temple.
Sri Anjaneyar is very special here. Whenever the Lord is carried out for procession, the first respects are paid to Sri Anjaneyar before the God is taken out.
This temple is protected and maintained by ASI. Lots of stone inscriptions are found along all the walls of the temple. These epigraphs belong to various periods starting Raja Raja Chola 1, Rajendra Chola and others. The inscriptions tell a lot about the grants made by various kings to the temple where the temple enjoyed huge popularity.
This temple stands a testimony for Indian heritage across centuries and explains about the glorious periods during the reign of Pallavas and Cholas where the kings not only showed interest in conquering places but also patronised education and health care along with religion to make a better society.
The temple is open between 08.30 am to 11.30 am and 4 pm to 6 pm on weekdays. On Saturdays and Sundays the temple is open from 08.30 am till 1 pm and from 3 pm till 7 pm.
