Wearing a mask nevertheless remains compulsory to circulate in the Nature Pavilion (marquee) on the Place d'Armes.
The mask can be removed occasionally for eating and drinking or when wearing is not possible due to the nature of the activity.

Conferences on the "Bourse":

Wearing a mask is mandatory to circulate in the conference room. It can then be removed once seated.
