This is due to the national ban by the federal government: At the moment, it is forbidden to hold any event anywhere in Switzerland.
Events with up to 300 people are permitted again from 6 June, meetings with up to 30 people from 30 May. Large events with more than 1000 people will remain prohibited until the end of August 2020. On our events page we will keep you informed about which events can be held and which are cancelled or postponed. In principle, we work with the organisers to find solutions for holding the events - in strict compliance with the conditions.
