The Paris Carnival occurs after the Feast of Fools and has been one of the major festivals of Europe since the sixteenth century or earlier.
Two types of events are part of the Paris Carnival: the walk of masks, and the processions.
In the walk of masks people in disguise make their way through the city surrounded by numerous onlookers.
The “fat days” processions occur on Sunday, Monday, and Mardi Gras (Tuesday) only. They end when the Promenade du Boeuf Gras (Procession of the Fat Ox) begins.
