Sri Nithyakalyana Perumal Temple

Sri Nithyakalyana Perumal Temple at Thiruvidandai is one of the most popular Thondai Nadu Divya Desams, located along the scenic East Coast Road (ECR) between Chennai and Mahabalipuram in Chengalpattu district. The deity's name "Nithyakalyana Perumal" means "the Lord of Eternal (Nithya) Auspicious Marriage (Kalyana)" — the Lord who is perpetually in a state of divine wedding celebration with His consort. This temple is thronged by devotees seeking the Lord's blessings for marriage, marital harmony, and the removal of obstacles to matrimony (known as "kalyana dosham" remediation). Thirumangai Azhwar praised this temple in his hymns, and the coastal setting near the ancient Pallava port of Mahabalipuram connects it to the broader maritime heritage of Thondai Nadu. The temple's proximity to the shore echoes the Azhwars' frequent metaphors of the Lord as the vast ocean of grace.
