Thiruvattar Sree Adikesava Perumal Temple is situated 6 km north-east of Marthandam and 30 km north-west of Nagercoil (in Kanyakumari district, Tamil Nadu). The temple is surrounded on three sides by rivers (Kothai,Parali and Thamirabarani).

Paraliyar takes a turn in this place and it is called vattaru and when the temple of Adikeasav Perumal was created it came to be known as Thriuvattaru.

This Temple is older than Padmanabha Swamy Temple at Thiruvananthapuram. Its structure is similar to that of Padmanabha Swamy Temple. The style and the architechture of this temple is taken as the sample to construct the Padmanabha Swamy Temple.

The idol of Adikesava and Sree Padmanabha are installed in such a way that they face each other. The lord is lying on his snake couch and has to be viewed through three doors. We could see Lord Shiva near the Lord Adikesava Perumal inside the sannidhi.

The Sri Adikesavaperumal Temple is a Hindu temple located in Thiruvattar, India and is one of the 108 Divya desams, the holy sites of Hindu Vaishnavism according to existing Tamil hymns from the seventh and eighth centuries C.E.

The temple is a picturesque setting surrounded on three sides by rivers namely, (River Kothai, River Pahrali and River Thamirabarani).

The Lord AdiKesavaSwamy means 'Foremost Friend'. Legend says that Lord AdiKesavaSwamy defeated the demon Kesi. The demon's wife prayed to the River Ganges and to River Thamirabarani and created a destruction. But it was in vain and she surrendered to the Lord. Thus, the formation of the rivers made in a circle came to be known as Thiruvattaru.

Vaikunta Ekadesi is celebrated with pomp and glory. Paal Payasam (Milk Kheer), Aval and Appam are delicious prasadams at this temple. The pujas are done in the same manner as that of the Sri Padmanabhaswamy temple,Thiruvananthapuram.

The temple architecture is Dravidian style architecture with wooden pillars, doors and roofs. The lord is lying on his snake couch and has to be viewed through three doors. We could see Lord Shiva near Lord Adikesava Perumal inside the sannidhi.
