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. 
The village itself is named after the deity of this temple. The main deity here is Lord Narasimhar. This is a beautiful rock cut temple. The temple and even the deity is carved out of a small hillock. Here the Lord is known as Sri Paatalaadri Narasimhar. In Sanskrit Paatalaadri means a reddish hill. The original name of this place itself is Paatalaadripuram.
According to temple sources, this temple has been referred in Brahmaanda Puraanam. Lord Vishnu took the form (Avataar) of Sri Narasimha and killed the demon king Hiranyakasipu. At the time of Narasimha Avataar, this place was surrounded by dense forests. A sage called ‘Jaapaali’ was performing Thapas, praying Lord Vishnu. As wished by him, the Lord gave dharshan to him in the form of Ugra (fierce) Narasimhar.
The main sanctum itself is a rock cut shrine on which the deity too is carved out of the hill itself. So, whoever wants to circumambulate around the temple has to actually go around the small hillock as Giri Pradhakshinam. Hence, Giri Pradhakshinam is very popular here.
There are Bali Peetams seen at certain directions, while going around the temple.
While walking around the temple, there is an Azhinjal tree in this temple, which is considered most sacred. It is said that this tree has mentions in the ‘Naachiyaar Thirumozhi’ composed by Sri Aandaal. People praying for marriage or children tie a small piece of thread from their clothes on the branches of this tree. By doing this with a wish, it is believed that their wishes are granted.
Sri Anjaneyar (Hanuman) is seen on the pillar adjacent to Dwajasthambha, where many people light Ghee lamps for the God.
While entering into the street of this temple, there are 4 pillars welcoming us, which look too ancient having beautiful sculptures.
The Theertham for this temple is called Suddha Pushkarani and Sthala Viruksham is Paarijaatham. 

Kodhai (Aandal) was carried in a palanquin to Sri Rangam and she entered the inner shrine of Sri Ranganathar and joined as the eternal light with the Lord.
