Chelamattom Sreekrishna temple is located at Chelamattom on Perumbavoor – Kalady road in Ernakulam district, Kerala. The temple lies on the banks of Periyar River. The main deities worshipped in the temple are Sree Krishna and Narasimha. The darshanam of Chelamattom Sree Krishna Swamy is towards east. Karkidaka Vavu Bali is of great importance in the temple.
The Upa Devatas worshipped in the temple are Ganapathy, Sastha, Nagayakshi and Swamiyar Samadhi.
As per history, initially the temple only had the prathishta of Narasimha. Sree Krishna murti was retrieved from the Periyar River and consecrated in the temple. The first vigraham of Sree Krishna was made of wood (dharuvigraham). The current shila vigraham (stone) was donated to the temple by Sakthan Thampuran. It is said that Shila vigraham was meant to be consecrated in Thiruvananthapuram but it was accidently installed at Chelamattom.
The temple is famous for Pithru Karmam (rituals associated with departed souls). This is because the Sankalpam of Sri Krishna here is the form in which he had resided in Yamapuri – the abode of Yama, the Hindu god of death.
The 8-day annual festival concludes on Thiruvonam nakshatra in Kumbham month.
