The most ancient and historically renowned temple, "Azhakodi Devi Mahakshethram," houses the deity "Bhadrakali" in a serene disposition. The temple comprises seven maternal incarnations: Brahmani, Maheshwari, Kowmari, Vaishanavi, Vaarahi, Indarni, and Chamundi. Additionally, a Sivalinga is also present within the temple. According to legend, the Samoothiri entrusted six of his generals to the temple "Arikkodikkavu," which is now famously known as Azhakodi Devi Mahakshethram. The Samoothiri had received an idol of "Bhavani Devi" as a gift from traders in Gujarat. He instructed the generals to place the idol beside the "Bhagavathi Idol" in the "Arikkodikkavu" sreekovil and worship it. During the end of Lord Krishna's era, it is more believed that the city of "Dwaraka" was entirely submerged by the sea, including the idol of "Bhavani Devi." Centuries ago, the location of 'Azhakodi Devi Mahakshethram' was an islet surrounded by the ocean in the west. However, after the installation of Devi's idol, the sea seemingly receded. Due to its islet form, the area was initially known as 'Thuruthnadu,' where 'Thuruthu' means islet and 'Nadu' signifies region. Over time, 'Thuruthunadu' evolved into 'Thiruthiyadu.'
