Arulmigu Sri Manonmani Mariamman Thirukoyil is a tiny family-owned theruvu koyil. It is owned and managed by the family that lives in a yellow building above a series of shops on Canteen Street (between Ambaltadayer Madam St and Nehru St), just across from the shrine. The person who used to officiate or otherwise oversee the temple was a government employee with the Slum Clearance Board, but he passed away in 2026, so his son Vishnu who was once his aide now sometimes takes charge of the alankaram and puja. The family typically hires an Iyer (Brahmin priest) to perform a puja in the mornings, and be present for a period during the sayarakshai time, in the evenings. The elderly grandmother tells us that the deity came from the Senkazhuneer Amman Koyil Kulam (water tank) on Pappammal Koil Street in Vaithikuppam. A Chettiar who lived nearby had brought and consecrated it, but then stopped and placed it in a well in the house of a carpenter nearby, as it is the custom to discard holy images and forms in water bodies rather than leaving them unattended or elsewhere. When the murti resurfaced from the well is when the brother of Shanta’s grandfather took it, installed it in a small space next to his dwelling (where the temple is now), and began pujas to it. So we know from this that the temple as such is approximately 3 generations old. There have been 2 Kumbhabhishekams done, with the help of Ganesh Gurukkal who is now the main priest at the Manakkula Vinayaka temple. The temple’s main festivities occur on Aadi Masam Fridays, with special alankaram for the deity.
