Chettippunyam village is located about 30 kms from Tambaram on west of GST Road, after Singaperumal Koil.Though the main deity of this temple is Sri Varadharaja Perumal, many people throng here to worship Sri Yoga Hayagreevar. One can see that the temple is always filled with school and college students coming here to worship Sri Yoga Hayagreevar, as He is the believed as the God for education, knowledge and wisdom.
It is said that, originally this temple had Sri Varadharaja Perumal only. Later during 1848, the idols of Sri Devanaadha Perumal and Sri Yoga Hayagreevar have been brought here from Thiruvaheendrapuram (near Cuddalore) to safe guard them from invaders.
Now, the main deity here is Sri Varadharaja Perumal and Goddess Sri Hemambuja Nayagi. The Urchavar of this temple is Sri Devanaadha Perumal. Sri Devanaadha Perumal is seen here with Prayoga Chakra on His right hand, which is a rare sight.Usually Hayagreevar is seen along with Sri Lakshmi in many places. But here unusually, He is seen meditating in Yogic posture with his legs folded. Many students visit this temple praying for their good scores in examinations. One can see students coming here with their pens, pencils, hall tickets etc. keep them at the Lord’s feet before taking their exams.
Many of these students write their exam roll numbers and wishes to perform well all along the walls. Though the temple administration has announced on the walls, not to scribble on them, no one seems to respect that. Even such lines like “I want to get engineering seat” are seen in many places.
Dwajasthambha is made of stone here on which Sri Garuda is seen facing the Lord, towards the sanctum.An Azhinjal tree is present at the northern side of the temple, where people tie a thread or a piece of cloth and pray the Lord for marriage, children and also to fare well in examinations.
A beautiful temple, especially granting wishes for students. 
This place was called as Chathurvedhapuram in ancient days and this temple’s main deity was Sri Chathurvedheeswarar and Goddess Sri Sivakami Amman. Sage Agasthiyar during his visit to this part of the country came here to worship the Lord. He was advised by a divine voice of Lord Shiva to install and worship Him under the Eru Azhinjal (
It is said that, those days this entire district had lots of Eru Azhinjal trees, which is considered most sacred. It is believed that any spiritual act performed under the Eru Azhinjal tree would be most divine and fetch desired results. There are 3 places in the present districts of then ‘Thondai Mandalam’, where Sage Agasthiyar had worshipped Lord Shiva under Azhinjal Tree. They are Azhisoor near Kanchipuram, 
According to the legend, Sage Agasthiyar as per the order of Lord Shiva collected the sand from the nearby Arani River, which was then called Brahmaaranya River, made Shiva Lingam out of it and started worshipping Him under this Azhinjal Tree everyday for 108 days, thus creating 108 Shiva Lingams. But to his surprise, when he completed creating 108th Shiva Lingam, all the 108 Lingams merged to become Lord Ganesha’s idol. Then, he was told by a divine voice that he forgot to worship Lord Ganapathi before starting the Shiva Pooja and hence all the deities merged together to form an idol of Sri Ganapathi.
Later Sage Agasthiyar made another Shiva Lingam and worshipped, which came to be known as Sri Ashtotheeswarar and also as Sri Nootreteeswarar. The God was called so, as Agasthiyar worshipped 108 Shiva Lingams at this place.
The Azhinjal tree under which Agasthiyar worshipped, remains till today and is 2500 years old now. Also the Swayambhu Ganapathy which formed from the 108 Shiva Lingams is seen under the same Azhinjal tree and is called as Sri Angola Ganapathy, as He evolved Himself under Angola (Azhinjal) tree.
There are 2 parallel shrines for both and each has separate Nandhi respectively.
Other deities of the temple are Sri Subramanyar with Sri Valli and Sri Devasena, Sri Surya Bhagavan (called Siva Suriyar) & Sri Kaala Bhairavar.
