Varahaperumal Temple is situated at Kumbakonam. The presiding deity is known as Varahaperumal. His consort is known as Boomidevi. There are shrines for Sri Vishwaksenar and Acharya Nikamanda Maha Desika.  Nagar is installed under the Tulsi plant in the prakara.   Those facing adverse aspects of serpent planets Rahu and Ketu worship Lord here lighting Deeps.  Varaha Theertham is outside the temple.  Just a little away from the temple are the Divyadesa temples of Lord Sarangapani and Lord Chakrapani. Even long before the time of Maha Pralaya-devastating tsunami floods, it is said that Lord Aadhi Varaha was in this place.  Maha Magam festival began to be celebrated in Kumbakonam after this event.  He is the first Perumal of this region.  On the Maha Magam festival, Kumbakonam Perumals Sarangapani, Chakrapani, Varadarajan, Rajagopalan and this Perumal-Aadhi Varahamurthi come to Cauvery for Theerthavari. Lord Aadhi Varaha Murthy in the sanctum sanctorum appears with Mother Bhoomadevi on His left lap.  Mother is facing Perumal in worshipping posture.  Those facing litigations in land property related matters, pray to Perumal for a solution.  During the Arthajama Puja-last puja at night in temples, ni-vedhana made of a powder from a root growing under the grass and mixed with rice flour and sugar is offered to Lord.  These flour balls are offered as Prasad to devotees the next morning.  As Lord rescued Mother Earth from deep Padala Loka, ni-vedhana made of a root growing under the earth is offered to the Lord. The procession deity, also Aadhi Varaha with His left foot on Adisesha is standing before Lord in a sitting posture.  The Varaha Salagrama with symbols of discus and conch is also before Lord.  Milk Abhishek is performed to Salagrama every day.
