Hello Hornfeld, please give us some more details and explain your inquiry to us. Kind regards, Sina

Hi, I think I can answer that. They realised that the building (and some others in the neighbourhood) was in grave danger of collapsing and had to immediately close down the Migros and evacuate the people who lived above it. I don't know when it's going to reopen.

There were also some articles in the newspapers.

Hi Hornfeld, please send your message to this e-mailadress: m-infoline@migros.ch

Kind regards,
