New regulations for concerts at the Philharmonie Berlin as of 1 April
In accordance with the Ordinance on Measures against the SARS-CoV-2 Coronavirus passed by the Berlin Senate, the regulations for concerts at the Philharmonie Berlin will change as of 1 April. The 3G rule as well as the associated verification checks at the entrances will no longer apply.
The mandatory wearing of an FFP2 mask will remain in force throughout the building and will also apply during concerts. Events in the Philharmonie Berlin may take place again with full occupancy of the halls from 1 April. As a result, tickets will once again be available for concerts that were already sold out.
