What is "thiruevvul"

Thiruevvul (or Veerarghavaswamy Temple) is a temple dedicated to Hindu god Vishnu, located in Thiruvallur, a town and headquarters in Tiruvallur district in the South Indian state of Tamil Nadu. Constructed in 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 counted as one among the 108 Divya Desams dedicated to Vishnu. Vishnu is worshipped as Veeraraghava Perumal and his consort Lakshmi as Kamalavalli Thayar.

The temple is believed to be of significant antiquity and is believed to be initiated by the Pallavas of the late 8th century AD, with later contributions at different times from Thanjavur Nayaks. The temple has three inscriptions dating from the Chola period. The temple has a seven-tiered rajagopuram (gateway tower) and enshrined within a granite wall. The complex contains all the shrines and the temple tank is located to the west of the temple.

Veerraghava Perumal is believed to have appeared to marry his consort Lakshmi in the place. The temple observes six daily rituals and three yearly festivals. The chariot festival and float festival, celebrated during the Tamil month of Chittirai (March–April), is the most prominent festival of the temple. The temple is maintained and administered by the Hindu Religious and Endowment Board of the Government of Tamil Nadu.
