The mass gathering on one of Brussels' iconic squares can"t go ahead for obvious reasons in times of corona, so people will have to celebrate and create a party atmosphere from their balconies, or inside their homes in their "bubble" of contacts.
A special show has been recorded. It will be shown on the website of "Bal National" and the Brussels TV channel Bruzz. This should make sure people can have a ball inside their homes. Your group of personal (close) contacts should not exceed 15 people though.
