Devanathaswamy temple, Thiruvanthipuram

Devanatha Hemabhujavalli Temple is a Hindu temple in Thiruvanthipuram, a village in the outskirts of Cuddalore in the South Indian state of Tamil Nadu, dedicated to the god Vishnu and goddess Lakshmi. Constructed in the Dravidian style of architecture, the temple is glorified in the Nalayira Divya Prabandham, the early medieval Tamil canon of the Alvar saints from the 6th–9th centuries CE. It is one of the 108 Divya Desams dedicated to Vishnu, who is worshipped as Devanatha and Lakshmi as Hemabhujavalli. Though the presiding deity is Devanatha and Hemabhujavalli, the temple is known for Hayagriva, the ninth avatara of Vishnu in the Dashavatara of Vishnu and a god of knowledge. The temple is the only historical temple in South India to have a shrine of Hayagriva on hilltop.

The temple in its current form is believed to have been built during the Medieval Cholas, with later expansion from Pandyas, Hoysala Empire and Vijayanagara Empire.
