Ambalapuzha Sree Krishna Temple, an ancient symbol of heritage is said to have been constructed by the ruler of the land, Chembakasserry Pooradam Thirunal-Devanarayanan Thampuran around 790 AD. The presiding deity of Parthasarthi, is likened to his traditional warrior form with a whip in one hand and a conch in the other. While the Sankam (conch) is an oft-seen symbol associated with Lord Visnu and his many incarnations, Ambalapuzha Sree Krishna Temple is one of the few rarities with its presiding deity wielding a whip.
This temple has a mythological connection to the famous Guruvayurappan. It is believed that Guruvayurappan visits the temple every day, even to this day, to partake of the skillfully prepared milk porridge that is served for naivedyam. The temple hosts The Amabalapuzha Temple Festival every year in commemoration of the installation of the deity. Aaraattu festival is yet another annual festival celebrated here.
