This temple which faces towards east, is situated on the Ernakulam Alappuzha national highway with a convenience of having a bus stop named as Aroor Temple stop. The presiding deity is Karthiyayani and sub deities are Sivan and Ganapathi. Five poojas are conducted, with reference to Puliyannur Tantric method. An eight-day festival is organized, incorporat ing an Arrattu which falls on an Uthram day during the month of Meenam. As per the epic, Villuamangalam, enroute in Aroor, noticed a divine light at the bottom of the Chootha tree, and hence installed the diety. The archeological records say, that the old statue which was destroyed by more the Dutch, lies in the temple pond. Another historical record is that, during the attack of the Dutch, the Brahmins living here fled. It was also told that this temple was situated in front of the "Jyothisha Kotta" of the King of Cochin. Till 1640 it was Moothedeth Kaimal family who was ruling Aroor and surrounding areas, with an agreement with the King of Cochin, to pay one tenth of the earnings they make here and it was been paid periodi- cally. Even though there arose a dispute regarding this payment and the Dutch interfered and a new agreement was established on April 6th 1710. During 1762, the province was handed over to Travancore, and it was later ruled by 72 Madambis, that is one record. But, originally, the possibility is that, the temple would have been with the Moothedath Kaimal's, and it would have been in this period that the Dutch attacked this province. History says that the destroyed temple was re-instated by Kannanku- langara Kaimal. Once in the destroyed Kanjira wooden floor of the temple, Kaimal saw the image of Devi, and in order to make Devi stay there itself, he requested not to go away, until he reaches back with a tender coconut, and he went home and hanged himself. This act was done for the sake of retaining the presence of Devi in the province., as per epic. His spiritual presence remains in the bottom of the Palm tree, and is called "Arrukolla Ammavan". There is also a possibility that Kaimal might have died during confrontation with the Dutch. Olden days this temple was known as "Kattil Pisharam". These terms are believed to have originated from Jainism and has transited to Hinduism through the Viashnava branch. and may be during the ages of Villiuamangalam it would have changed to be a Vaishnava Durga Temple. It is believed that Aroor Karthiyayani temple is one among the 108 Durga temples.
