Thiruvayamkudy Mahadeva Temple, with a history dating back to around 1000 AD, venerates a central Shivalingam as its main deity. Legend has it that an aged Brahmin from Ayamkudy, a devout follower of Vaikathappan (Lord Shiva), the principal deity of the renowned Vaikom temple, was unable to travel there for worship. In response, the deity Vaikathappan manifested at Ayamkudy, leading to the eventual construction of the temple, now prominently positioned at the heart of the village. Originally under the care of seven Ooranma families, only five, including Pattamana Illam, Ettikkada Mana, Irishi Illam, Marangatta Mana, and Neithasseri Mana, still have surviving members. The temple features a Rahasya Ara more (secret cabin), serving as a reservoir for the divine power of the idol. Protected by sturdy granite stones, a lamp is ceremoniously lit in front of the cabin before the main lamps, and it is guarded by a symbolic serpent. Additionally, the temple premises include a well with a perpetual spring of cool water believed to have a connection with the Ganges, stemming from the divine head of Lord Shiva. Despite being situated at the highest point in the village, the water level in this well has never dropped below a certain point, even when other wells in the area have run dry. Ayamkudy village has long been a hub for Rig Veda learning, attracting numerous experts. Rig Veda education, a seven-year endeavour, has historically been associated with the temple, emphasizing the deep-rooted connection between spirituality and knowledge in this sacred place.
