 The three-headed demon "Trishira", who meditated on Thayumanavar near the present-day city to obtain favours from the god.An alternative derivation, not universally accepted, is that the source of the city's name is the Sanskrit word "Trishirapuram"—"Trishira", meaning "three-headed", and "palli" or "puram" meaning "city".As per another legend, due to a fight between Adisesha (serpent god) and Vayu (Wind god) to seek ownership of Himalayas, the three pieces of the mountain fell to three different places.
