This massive, beautiful and ancient temple is located in a small and verdant village called Ambasamudram on the banks of the Thamirabarani about 40 kms or 1 hour west of Thirunelveli. Although not a Paadal Petra Sthalam, it is mentioned in the 6th Thirumurai in passing and is thus classified as a Paadal Vaippu Thalam. It was called Ayaneeswaram (Ayan is Brahma) in the Thevaram. Some believe it is the first of the Navakailasa temples and is dedicated to the Sun. Some believe that the ancient temple in Papanasam close by is the real first Navakailasam.
Many dynasties have contributed to the construction of this vast and grand temple. The great emperor Raja Raja Cholan was very fond of this temple and made many contributions. With 3 tall gopurams and 7 vimanams and innumerable sculptures, it is an architectural masterpiece and hidden treasure. The Nandi here is the largest in the region and has an animated and beautiful appearance. The solid massive doorway is intricately carved by artisans from Kerala and fortified. Much of the structure that we see today is from the Nayakkar renovation in the late 1500s. There is a spot in the outer prakaram (the locals will show you) from where you can see all the towers.
The temple has a bit of a forlorn look. It is very much an active temple but needs some repair soon. Since 2017 renovation work in most old temples have been frozen due to a court order. There is an ongoing battle between those who favour renovation (which is repair with modern techniques and material) and those who insist on restoration (which is careful repair that sticks to the original design and materials). There are merits to both arguments. Restoration is time-consuming and very expensive. Difficult for large temples. Local people will object to the ASI ( Archeological Survey of India) taking over these temples. The single Kurukkal family who manages this temple does not have the political clout to expedite things. The temple is solid. A fresh coat of paint will make it shine. The Kumbabishekam or Kudamulukku (the 12 yearly renewal of temples) is 4 years overdue at this temple due to this controversy.
