The famous Thrissur Pooram festival, is held annually at the precints of the Vadakkumnathan temple is a joint effort of nearly nine participating temples.

The two main participating temples, the Thiruvambadi and the Paramekkavu temples add grandeur to the Pooram. Months before the festival, the two temple groups are actively involved in the making of the colourful parasols or the Muthukkuda.
The royal umbrellas are made of silk and satin and are laced with white metal and sequins.

Kudamattom is the ceremony during the Thrissur Pooram festival, when these long stemmed glittering umbrellas are exchanged. The rhythmic changing of the umbrellas along with the traditional musical orchestra, Pandimelam, played in the background, is a remarkable event.
