Irattai Tirupati Temples refer to two temples of the Nava Tirupati, namely, the Devapiran temple and Aravindalochanar temple, which are dedicated to Vishnu.
They are part of the nine "Divya Desams" located along the Tiruchendur-Tirunelveli route in Tamil Nadu, India on the banks of Thamiraparani river. The two temples are located adjacent to each other. All nine temples are part of the 108 temples of Vishnu revered by the 12 poet saint Alvars.
The Irattai Tirupati is a Ketu Sthalam, sacred to the deity Ketu. Constructed in the Dravidian style of architecture, the temples are dedicated to Vishnu who is worshipped as Devapiran and Aravindalochanar and Lakshmi as Varagunavalli and Karuthadankanni.
A granite wall surrounds both the temples, enclosing their shrines. The rajagopuram (the temples' gateway tower) has a flat structure. The temples follow the Tenkalai tradition of worship. Six daily rituals and three yearly festivals are held at the temples.
