Tiruvelukkai located in Kanchipuram in the South Indian state of Tamil Nadu, is dedicated to the Hindu god Vishnu. Constructed in the Dravidian style of architecture, the temple is glorified in the Divya Prabandha, the early medieval Tamil canon of the Azhwar saints from the 6th–9th centuries AD. It is one of the 108 Divyadesam dedicated to Vishnu, who is worshipped as Azhagiya Singar and his consort Lakshmi as Amruthavalli.
The temple is believed to have been built by the Pallavas of the late 8th century AD, with later contributions from Medieval Cholas and Vijayanagar kings. The temple has three inscriptions on its walls, two dating from the period of Kulothunga Chola I (1070–1120 CE) and one to that of Rajadhiraja Chola (1018-54 CE). A granite wall surrounds the temple, enclosing all the shrines and two bodies of water. There is a four-tiered rajagopuram, the temple's gateway tower, in the temple.
Azhagiya Singar is believed to have appeared to slay Hiranya, the demon king. Six daily rituals and three yearly festivals are held at the temple, of which the Krishna Janmasthami festival, celebrated during the Tamil month of Aavani (August–September), being the most prominent. The temple is maintained and administered by the Hindu Religious and Endowment Board of the Government of Tamil Nadu.
