Originally, this temple served as a Vishnu or Krishna Temple, with a history dating back approximately 1500 years. The temple, following the consecration of the idol of Annapoorneshwari by Amma, was constructed under the patronage of Avittamthirunal Raja Raja Varma of Chirakkal Kovilakam. In Hindu mythology, it is believed that the Goddess arrived from Kashi alongside two other goddesses or devis (Kalarivathukkal and MadaiKavil Amma) and a boatman, aboard a golden ship, and disembarked at Azhi Theeram, which is now known as AayiramThengu. The Puna Prathistha ceremony took place in 1994, during the month of Kumbham in the Malayalam calendar, on Pooyam Nakshtram. This day is now more celebrated annually as Prathista Dinam. The main festivities at the temple commence in the Malayalam month of Medam Shankramam (15 April) and continue for the following seven days. Additional festivals celebrated at the temple include Shiva Rathri, Navami, Ekadashi, and more. The temple is currently administered by the Malabar Devaswom Board and maintained by the Temple Committee. One distinctive feature of this temple is that it was constructed from a single type of rock, and both the Sreekovil of Annapoorneshwari and Krishnan are of identical size according to Vasthu principles, signifying equal importance for both the goddess and the god. The temple's entrance is in front of Krishnan's Sreekovil, and there is no direct entrance to Annapoorneshwari's Sreekovil. This design dates back to ancient times when it was considered inappropriate for women from Brahmin families to be seen directly (Antharjanam). As a result, there is a small window in front of the Sreekovil where the idol can be seen from outside. This temple is one of only two Annapoorneshwari temples in Kerala. It was constructed using polished stones and assembled using avil and belam (a mixture of flattened rice and jaggery). Adjacent to the temple is the temple pond, Ambala Kolam, covering approximately 2.5 acres. At its centre is the Pole, also known as the stump. The four main entrances of the Chera were constructed using large layers of rock that were laid parallel to each other. Additionally, the Chera features a Kollapura (used by poojaris for bathing), located to the southwest of the Chera.
