The Naravoor Sri Mahavishnu Temple, in its current manifestation, was constructed in the 1900s by Sri Ayilliath Narayanan Nambiar, affectionately known as Judge Valiachan due to his retirement as the District & Sessions Judge of Thalassery District Court during the British India era. His wife, Ningileri Thayillath Parvathy Amma, hails from the lineage of Ningileri Thayillath Meenakshi Amma, fondly referred to as "Muthachi."  Judge Valiachan's decision to build the temple was prompted by family history. It was revealed that their daughter, Kanthimathi, faced mental illness and passed away at an early age. Seeking answers to the family's challenges, Judge Valiachan consulted a family astrologer, who, through a Prasnam more (query session), advised reinstating and worshiping an unnoticed idol of Mahavishnu lying in the family property at Naravoor. Legend holds that the Naravoor property, housing the Mahavishnu temple, was originally owned by Namboothiri families during the 1700-1800 period. The Chaathaadi Mana, a Namboothiri Illam, maintained a small temple with deities of Vishnu and Durga. However, during Tippu Sultan's invasion of Malabar in the 1780s, many temples, including this one, were desecrated and destroyed. The Namboothiri families, foreseeing the danger, had hidden the deities in a well before escaping. Over time, the land changed hands and eventually came into the possession of Muthaachi (Meenakshi Amma) in the 1850s, the founder of the Thayillath branch of the Ningileri Tharavad. Guided by astrological predictions, Judge Valiachan retrieved the Vishnu idol from the abandoned well at Naravoor. Despite being broken into pieces, the dark granite idol was meticulously restored and enshrined in the newly constructed temple. The construction of a temple under the ownership of an individual was a rare accomplishment at that time. Consequently, the temple became the property of the Ningileri Thayillath family, with the responsibility of its sustenance and upkeep falling on the descendants of Thayillath thavazhi.
