The Adi Kalyana Jagannatha Perumal temple is situated in Thirupallani, which is a village 10 km away from Ramanathapuram district. The temple has a 5 tiered rajgopuram which means the main entry tower facing the east direction. The memorial of Sri Adi Jaganatha displays the representation of Adi Jaganatha, Bhudevi and Sri Devii in sitting posture. The companion of Adi Jaganathar is Padmasini and Sri Padmasini is accommodated in a separate memorial. Lord Dharbasayana Ramar has a shrine in which the deity is in a leaning posture. There is also a metal portrait of the Lord Krishna from 13th century of the Pandya period. The metal portrait depicts Lord Krishna dancing on a snake, which is a very unique historical representation of the Lord Krishna.

The priests of the temple carry out the poojas on every day basis and also during festivals. The priests in the Vishnu temples belong to the Vaishnavite community, a Brahmin subcaste and so does the Adi Kalyana Jagannatha temple. The daily rituals of the temple are carried out six times a day namely Ushatkalam, Kalasanti, Uchikalam, Sayarakshay, Irandumkalam and Aradha Jamam. Nadhaswaram which is a pipe instrument and Taevil which is a percussion instrument are played in the final stage of worship and simultaneously the priests recite the religious commands of the Vedas, and worshippers gather in front of the mass. There are also weekly, monthly as well as fortnightly rituals that are carried out in the temple. The Panguni Bramotsavam for Rama Navami and Adi Jagannathar Utsavam during the month of Chittirai are the two major festivals celebrated. Other main festivals celebrated in the Vishnu temples in South of India like Vaikunda Ekadeshi, Pongal ,Krishna Jayanthi and Diwali are the other major festivals which are usually celebrated in Vishnu temples across Southern India.
