The history of the temple or its origin could be dated back as early as 1000 AD. The main idol is a Shivalingam, supposed to have appeared on its own in the homagni in a Brahmin's house at Ayamkudy. This Brahmin was an ardent devotee of Vaikathappan, the main deity of the famous temple at Vaikom away. According to legend, he was unable to get to the temple for worship due to his old age, so the deity of that temple appeared in his Upasana Homagni. The temple was constructed later and it stands presently as the top center of the village. There seem to have been seven Ooranma families of the temple; however, only five still have living members. The present Ooranma Families include Pattamana Illam, Ettikkada Mana, Irishi Illam, Marangatta Mana and Neithasseri Mana. The temple houses a Rahasya Ara where the divine power is located. This is considered a reservoir for the power of the idol. The cabin is well protected with granite stones. A lamp is lighted every day in front of it, before the other main lamps are lighted. A serpent is believed to be sitting in front of this to safeguard the place. There is also a water well, with a perennial spring of cool water. This believed to have a connection with the Ganges, originating from the divine head of Lord Shiva. Although the well is situated in the uppermost part of the village, its water has never gone below a certain level, even when most of the wells in the village have dried up. The Ayamkudy village has been a center for learning Rig Veda, with many experts resident in the village. Education in the Rig Veda takes nearly seven years; the coaching was always associated with the temple. Until recently, the temple has also been known for its assets in the form of land. However, the situation has dramatically changed in the recent past.
