The Puri temple is famous for its annual Ratha yatra, or chariot festival, in which the three principal deities are pulled on huge and elaborately decorated temple cars. These gave their name to the English term Juggernaut. Unlike the stone and metal icons found in most Hindu temples, the image of Jagannath is made of wood and is ceremoniously replaced every twelve or nineteen years by an exact replica. It is one of the Char Dham.
