Constructed in the Ancient Indian style of architecture, the temple is glorified in the Nalayira Divya Prabandham, the early medieval Tamil canon of the Alvar saints from the 6th–9th centuries CE.

It is believed Vishnu appeared in his dream and asked him to dedicate the garland worn by Andal to him daily, which is a practice followed during the modern times.

A granite wall surrounds the temple, enclosing all its shrines, the garden where Andal is believed to have been born and two of its three bodies of water.

The temple is maintained and administered by the Hindu Religious and Charitable Endowments Department of the Government of Tamil Nadu.

The girl Kothai was thus named Andal and was referred as Chudikodutha Sudarkodi (lady who gave her garland to Vishnu).

The practise is followed during modern times when the garland of Andal is sent to Azhagar Koyil on Chitra Pournami day where the presiding deity Lord Kallazhagar entering into River Vaigai with the garland worn by Goddess Andal and Tirumala Venkateswara Temple during [Garudostavam during the Tamil month of Puratasi (September - October)].

As per some accounts, the original structure was constructed by Tribuvana Chakravarthy Konerinmai Kondan Kulasekaran and the Andal temple and 194 feet Rajagopura was built by Barathi Rayar of Vijayanagar king.

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

A granite wall surrounds the temple, enclosing all its shrines, the garden where Andal was found and two of its three bodies of water.

The tower is originally believed to have been built by Periyalvar with the prize money he obtained from religious debates in the court of Vallaba Pandya in Madurai.

The second hall from the entrance towards the sanctum, the Kalyana Mandapa, houses huge life-size sculptures of Mohini, Rama, Kamadeva, Rati, and many other deities.

The sanctum in the second level approached through a flight of steps houses the image of Vatapatrasayi in a reclining posture and his consorts, Lakshmi (Sridevi) and Bhudevi, are shown attending to him at his feet.

The banyan tree whose leaf is known as Vatapatram, on which Vishnu is said to rest in the form of a baby during deluge, is at his head, behind Bhrigu.

Images of Panchamurtis - Tumburu, Narada, the Sanatkumaras, Kinnara Mithuna, the sun and the moon gods are shown all around Rangamannar as well as representations of Villi and Puttan are seen at his feet.

[13] The composite columns of Virabhadra holding sword and horn are found be additions of the Vijayanayagara kings during the early 1500s.

She is credited with the Tamil works of Thirupavai and Nachiar Tirumoli that are still recited by devotees during the Winter festival season of Margali.

Adopted by her father, Periyalvar, Andal avoided earthly marriage, the normal and expected path for women of her culture, to marry Vishnu.

The temple rituals are performed six times a day: Ushathkalam at 7 a.m., Kalasanthi at 8:00 a.m., Uchikalam at 12:00 p.m., Sayarakshai at 6:00 p.m., Irandamkalam at 7:00 p.m. and Ardha Jamam at 10:00 p.m. Each ritual has three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Vatapatrasayi and Andal.

After early morning special pujas, the presiding deities, Sri Rengamannar and Goddess Andal are taken in decorated palanquins to the car.

[18] The festival marks the adoption of presiding deity, Andal, by Periyalvar after he found her near a tulasi plant in the garden of Vatapatrasayi Temple at Srivilliputhur on the eighth day of the Tamil month of Adi.

With the efforts of Vanamamalai Jeer, the head of a monastic institution, the temple car was modified with hydraulic wheels to ease the movement.
