 A special event in the royal family – a coronation, birth, baptism, marriage, or simply the entry of the king or queen into the city – was usually the occasion for a public celebration.Large and colorful processions frequently took place to mark special days or events, such as a military victory, or ask for God's protection in the event of a flood or an outbreak of the plague.The most important annual procession took place on the Day of Saint Denis; it proceeded from the Châtelet fortress to the Basilica of Saint-Denis and was led by the Bishop of Paris and the clergy of Paris, followed by the members of religious orders and representatives of all the guilds and professions of the city.
