Nithya Kalyana Perumal Temple must be at least 1000 years old and it is believed to be built by Chola kings. The temple is not very huge but very beautiful. Thiruvidandai or Nithya Kalyana Perumal Temple is one of 108 Divya desam (108 most important temples of Lord Vishnu). It is near Chennai around 40 km. It is Varaha Kshetram. It is famous for marriages. The temple was built by Pallavas. It is near Seashore. It has a large temple tank in front of the temple. It is quite an old temple. There is a separate shrine for Komalavalli Nachiyar. The Lord here stands on Adisesha and holds his consort on his left side. There is also separate shrine for Andal. The Temple follows Thenacharya Sampradayam. Sage Markandeya and King Mahabali had visited the kshetram. Even today many pilgrims come here and get the blessings of Lord Nithyakalyana Perumal. Those who wants to get married would be offering two garlands to Lord. After Puja, the priest would give one of the garlands. The person should wear that garland and do Pradakshinam. This is practiced, so that marriage would be fixed soon to the bhaktas.

At this temple, one finds the Lord in a unique standing posture facing East. While one leg is on the ground, the other is on Adhisheshan and his wife. And he is seen balancing Goddess Agila Valli on his left thigh. Lord Vishnu came here as a Brahmachaari and married one girl a day. Unmarried people will find their life partner immediately if they visit this temple. This place is also called Nithya Kalyana Puri, Sri Puri and Varaaha Puri. As the Lord merged 360 girls into one and appeared with the Goddess on his left on the last day, this place is called Thiru- Idanthai (Thiru-Goddess, Idanthai-left side), which in course of time became ThiruVidanthai.
