Vallam is a small village near Chengalpattu. While going from Chennai, one has to take left from Chengalpattu on the Mahabalipuram Road and Vallam is located on the 3rd Km from Chengalpattu. A small pathway from the main road leads to the village.Vallam has a beautiful small hillock on which two wonderful rock cut temples are found. There are steps leading to the temples. According to the inscriptions found, these temples are said to have been built during the period of Mahendravarma Pallava. Inscriptions also reveal the ancient name of the place as Valla Naadu under Kalathur Kottam.
On the left hand side there is a temple for Lord Shiva called Sri Vedhaantheeswarar. Goddess here is Sri Gnaanaambigai. This is perhaps the only place where one can have dharshan of Sri Vinayagar, Sri Subramanyar, Lord Shiva, Sri Ambaal and Sri Sandigeswarar from the same place where we stand. Lord Muruga here is called as Sri Muthukumaaraswami.
Unlike other Shiva temples, here Goddess Sri Gnaanaambigai is facing the east. Sri Gnaanaambigai looks like a very new idol with clear details and is beautifully decorated with silk saree. The face has so much of Thejas and benevolence. The Dwarapaalakaas are so exquisitely sculpted in life size. The Soolam and Mazhu, which are the weapons of Lord Shiva, are carried by the Dwaarapaalakaas here. It is said that, in this temple, during Pradhosham, the Abishegams are first performed to Dwaarapaalakaas and then to Sri Vedhaantheeswarar and finally to Sri Nandhigeswarar. Now a concrete structure is built around this temple for convenience.It is said that during the sunrise, the rays from the Sun fall directly on the Lord like a garland.
On the right hand side there is a temple for Sri Giri Varadharaaja Perumaal. Sri Perumaal is seen here with his consorts Sri Devi and Bhu Devi. Dwaarapaalakaas are found outside the sanctum.
Unusually, Sri Durgai is found in the Perumaal temple facing south instead of north as found in Shiva temples. According to the inscriptions, it is found that a lady called Kommai (கொம்மை), daughter of a Pallava King has installed Sri Durgai in this temple 1300 years back.
The temple pond is called as Sivaganga Pushkarani, the water from which is used for Abishegams to the Gods.Pradhosham and all other Saivite and Vaishnavite festivals are done here at these temples. On usual days, priest visits the temple once a day for daily rituals. But one can have dharshan even in the absence of the priest.
Nice temple with serene ambience with excellence of Pallava architecture.

It is also said that the names of this place in ancient days were as Kosai Nagar, Koyattipuram and Prayachithapuram. Kulothunga Chozha is said to have ruled in the 12th Century and hence it is said that the temple was constructed during his period.
Usually, Vaikunda Perumaal temples will have the presiding deity in sitting posture. But here Perumaal is seen in standing posture along with Sri Devi and Bhu Devi.
This temple is also famous for its shrine for Sri Rama and Sita Devi. Sri Rama and Sita are found just outside the sanctum unusually on normal clothing instead of being dressed like King and Queen. Sita Devi is seen on a regular Saree with her hair do (called Kodaali Kondai) as an ordinary woman. It is made to signify their posture when they spent 14 years in the forest.
In another place, Sita Devi is also seen as a pregnant woman, as She gave birth to Lava and Kusa at Sage Valmiki’s Ashram, after She was exiled to forest.
Goddess Sri Kanagavalli Thaayaar is present in a separate shrine on the outer praakaaram at the southwest side of the temple. Goddess is so beautiful, decorated with all Her ornaments.
Sri Aandaal shrine is located at the northwest corner of the temple.
There are 3 trees uniquely grown very close to each other. There is one Vilvam tree between 2 neem trees on its either sides. It is said that Vilvam signifies Lord Shiva and one of the Neem tree represents Sri Parvathi and another Neem tree signifies Her brother Lord Vishnu. It is believed that it is like the wedding posture of Lord Shiva where Lord Vishnu presides over their marriage by joining their hands together. A Vilvam and Neem tree inside a Vaishnavite temple is a very rare sight.
There is a separate shrine for Sri Anjaneyar at the opposite side of the temple, where Sri Anjaneyar is seen facing west towards the temple.
The theertham for this temple is ‘Lava Kusa Theertham’ which is believed to have been created by the two sons of Sri Rama. The same tank serves as Theertham for Sri Kurungaaleeswarar temple, which lies just adjacent to this temple.
The presiding deity is Sri Veda Narayana Perumal. This temple is called Mathsya Avataara Sthalam as Lord here is seen in Mathsya Avatar, which is the first and foremost avatar (incarnation) among 10 avatars of Lord Vishnu.
Lord Vishnu, took the avatar in the form of a fish (Mathsya in Sanskrit), went deep into the sea and fought with Somukasura. Somukasura was defeated in the battle by Lord Vishnu, who brought back 4 Vedas and handed over to Lord Brahma safely. As God saved Vedas here, he is known as Sri Veda Narayana Perumal.
