The temple is located on the Southern banks of Poondi reservoir on the Thiruvallur - Thiruthani road, 5 km (3.1 mi) away from the town.

The temple complex covers an area of one acre and all its shrines are enclosed with concentric rectangular walls.

In modern times, the temple is maintained and administered by the Hindu Religious and Charitable Endowments Department of the Government of Tamil Nadu.

[1] Another legend is that once, while Vishnu and Brahma contested for superiority, Shiva appeared as a flame, and challenged them to find his source.

Brahma took the form of a swan, and flew to the sky to see the top of the flame, while Vishnu became the boar Varaha, and sought its base.

The flower was cursed that it won't be used during the worship of Shiva, but an exception was given during Shivaratri festival in the temple.

The second one is a broken inscription on the Western wall indicating grant of paddy to the temple by a private party during the third regnal year of Kulothunga Chola I (1070-1122 CE).

The shrine of Pasupathi Nayagi (also called Mohanambal), facing East has a gopuram type roof.

[4] Tirugnana Sambandar, a 7th-century Tamil Saivite poet, venerated Vaseeswarar in ten verses in Tevaram, compiled as the First Tirumurai.

The temple rituals are performed three times a day; Kalasanthi at 8:00 a.m., Uchikalam at 12:00 a.m. and Sayarakshai at 6:00 p.m. Each ritual comprises four steps: abhisheka (sacred bath), alangaram (decoration), naivethanam (food offering) and deepa aradanai (waving of lamps) for Vaseeswarar and Gnanambigai.
