The spectacular tradition of rose petals fluttering down through the oculus of the Pantheon is scheduled on Sunday 31 May from 10.00 following Mass for the Feast of Pentecost. However, due to the covid-19 crisis, this year the annual tradition will take place behind closed doors for the first time, broadcast live from the Pantheon's official website, beginning at 10.00.

The ancient ceremony involves fire-fighters dropping tens of thousands of rose petals 43 metres into the interior of the Pantheon, symbolising the Holy Spirit’s descent to Earth. Due to its popularity, the event normally sees people queuing several hours in advance, as entry uusually ceases once the crowd reaches a capacity number of about 800 visitors.
