Massive house 1970 - Crack in basement wall, please provide an assessment

Hello everyone. Seven years ago we bought an old building (semi-detached house) from 1970 - solid house. We have a crack in the basement room - on the wall that goes to the other half of the house. Is something like this dangerous? I never thought about it but still wanted to ask. The crack was already there when we bought it. Thanks for your initial assessment!

The small crack? Psh, I would never have thought about that either.

Well, it does go all the way from the ceiling to the floor. But still inconspicuous?

I'm not a structural engineering expert, but I think it's uncritical. Just a layman's opinion!

Hi, I would mark the extent with pencil marks or regular photos. If the crack doesn’t get bigger and no moisture comes through, it is probably not a big problem. If the crack grows larger over the years, there is certainly urgent need for action. Best regards, Andreas

OH god! House is collapsing...

no kidding, normal settlement crack. Documenting
