Thrissur Pooram

Drawing huge masses of people and involving meticulous planning, this festival has been described as the ‘mother of all poorams’. It is essentially an assemblage of the ten deities from nearby temples paying homage to their lord and benefactor, Vadakumnathan. Principal participants are the two temples of Paramekkavu and Thiruvambadi; their friendly and much feted rivalry enlivens the proceedings. The pooram culminates in a parade of thirty elephants from adjoining temples and some stunning fireworks in the wee hours of the morning.

Vishu
The Malayalam New Year is celebrated by bursting crackers and going to temple.
