History.
There is one inscription in the temple and five copper plates from the 16th century indicating various grants to the temple. It is understood from the inscriptions that the temple was built by Krishnappa Nayak (1563–72), the son of Viswanatha Nayak, the founder of Madurai Nayak dynasty. Krishnappa is attributed to the construction of the precincts around the temple and the soaring temple tower. Krishnappa Nayak also laid four streets around the temple for the smooth passing of the temple car. The village was originally named Thiruvenkatapuram and got changed to Krishnapuram during the rule of Krishanppa Nayak. Deivachillayar (Mayilerum perumal), the son-in-law of the minister of Viswanatha, played a key role in the construction of the temple. Detailed account of his work in the temple is extolled in "Deivachillayar vidu thoothu" by Kumaraswamy Avadaniyar and also in the "History of Tinnelvelly" by Caldwell.
The copper plates from Sadasiva Raya of Vijayanagara Empire indicate grants to light lamps perpetually and lay gardens. There were six villages to allow the continuous functioning of the temple. The villages Ariyakulam, Kodikulam, Kuthukaval, Puthaneri, Pottukalam, Sriramakulam and Alikudi were donated to the temple for the performance of daily poojas. An Agraharam with housing for 108 Brahmin families well-versed in Vedas and "agamas" was established.
The temple was originally administered as a subtemple of Ramaswamy temple of Tirunelveli, but came under the administration of Nelliappar temple from 1973. It came under the dominion of Tiruchendur Devastanam from 1986.

There is a separate shrine of Alamelumangai in the third precinct, which also houses the festival image.

Festival.
The temple follows the traditions of the Thenkalai sect of Vaishnavite tradition and follows "Pancharathra aagama". It is inferred from the inscriptions that the temple priests performed pooja five times a day during the 16th century, strictly following "agamic" tradition. In modern times, the temple priests perform the "pooja" (rituals) during festivals and on a daily basis. There are weekly, monthly and fortnightly rituals performed in the temple.
The temple had originally received endowments to perform the eleven-day annual Brahmotsavam festival, ending with Teppotsavam, the float festival. The festivals are not celebrated during modern times. The ten-day annual Vaikunta Ekadasi during the Tamil month of "Margazhi" (December - January) is the major festival celebrated in the temple, along with the other common Vaishnavite festivals.
