Athachamayam is the only one day in a year when all the people, irrespective of caste and creed were allowed to enter the Kottakkakam (Fort). After the flag hoisting and the lighting of the lamp, a ceremonial parade is taken out in the narrow streets of Tripunithura town, headed by Lord Mahabali. Art forms of ancient and modern times, floats and folk dances add colour and substance to this procession. Thousands of people participate in the parade. It is an occasion to witness almost all folk art forms of the state.
