The Thrissilery Shiva Temple, nestled in the heart of Wayanad, stands as a revered pilgrimage destination with a rich history. This ancient temple, among the oldest in Kerala, is dedicated to Lord Shiva and shares a deep connection with the famed Thirunelli Temple in Wayanad. Its architecture boasts unique proportions and intricate carvings, creating a serene and tranquil ambiance. A noteworthy feature is the presence of a small shrine dedicated to Jala Durga, situated within a water body originating from the Papanashini River near Thirunelli. Located along the Mananthavady-Mysore Highway in Wayanad district, this renowned Hindu temple lies 8 km from Mananthavady, 20 km from Thirunelly, more and 37 km from Kalpetta. It holds a special place in the hearts of devotees, not only as one of Kerala's prominent Shiva temples but also as a significant pilgrimage site in Wayanad. Lord Shiva is the principal deity of this sacred place, and an interesting belief surrounds the temple: ancestral rites performed at Thirunelly are considered incomplete without subsequent offerings at Thrissilery Shiva Temple. Within the temple grounds stands a shrine dedicated to Jala Durga, believed to have been installed by Parasurama, and the temple tank remains perennially filled. The temple's architectural style bears resemblance to the Vishnu Temple at Thirunelly, with its idols and carvings showcasing exquisite artistry. Lord Shiva's divine form exudes enchanting beauty, and devotees often present offerings of flowers, bananas, and coconuts. This temple warmly welcomes visitors of all backgrounds, regardless of religious affiliations. The annual festival of Thrissilery Shiva Temple takes place during the Malayalam month of Meenam, falling in March-April, while another significant celebration, Puthari, occurs during the month of Thulam, which spans October-November.
