Authorities remove beam placed on Christmas Day to recreate Eisbach wave, which vanished in October

A row over the disappearance of a famous river surfing wave in Munich has escalated after authorities removed a beam inserted over Christmas to recreate the attraction.

The Eisbach wave on a side branch of the Isar River had been a landmark in the Bavarian city since the 1980s but it vanished in October after annual cleanup work along the riverbed.

Activists had placed a beam in the water early on 25 December to partially recreate the wave, according to German media reports, and hung a banner above the water that read “Merry Christmas”.

But a spokesperson for the Munich fire service told Agence France-Presse that the “installation” was removed on Sunday at the request of city authorities.
