Many of the temples in Kerala hold festivals on specific days of the year.[39] A common characteristic of these festivals is the hoisting of a holy flag which is brought down on the final day of the festival after immersing the deity.[40] Some festivals include Poorams, the best known of these being the Thrissur Pooram.[41] "Elephants, firework displays and huge crowds" are the major attractions of Thrissur Pooram.[42] Other known festivals are Makaravilakku,[43] Chinakkathoor Pooram, Attukal Pongala and Nenmara Vallangi Vela[44] Other than these, festivals locally known as utsavams are conducted by many temples mostly on annual basis.
