The name Ettukudi is derived from the fact that it is surrounded by etti (Strychnine) trees and that there are Shiva temples in eight directions. Ettukudi Murugan or the Subramania Swami temple at Ettukudi, though not one of the Arupadai Veedu (Six Sacred Temples of Lord Murugan), achieved popularity mainly through veneration in songs by the 14th century Tamil poet Saint Arunagirinathar and today, through folk music and other devotional songs.The Thala Virutcham (temple tree) of this temple is Vanni tree and the theertham (temple tank) of this temple is Saravana Poigai.
