If you look carefully at this photo, you will see a number of tall poles in the grassy area. We have seen these in various places. Having arrived in Switzerland 15 days after the national holiday, we wondered if these poles had something to do with the holiday. Perhaps there were flags on top? Streamers or banners?
H asked someone at the lab about this and told them our theory. They smiled and said they liked our idea better than the actual fact. Actually, these poles mark out the size of a new building slated for that site. One can more easily imagine not only the square meterage (?) on the ground, but how tall the future building will be (and how much it will block your view).
