Only five people participated at the flag hoisting ritual held here on Sunday at Paramekkavu and Thiruvambadi temples due to the COVID-19 lockdown guidelines.
It was decided earlier this month that this year's festival will be held without gathering of people.
The main attraction of Thrissur Pooram, which showcases fireworks and parading of elephants falls on May 3. But this year it has also been cancelled in the wake of COVID-19.
