Quite a nice building but I found it to be a little boring. The office building itself is apparently world renowned for its amazing ecologically friendly design. They use the water from the Vltava to operate the cooling system in the building which is pretty cool. but as we took the tour of the office, the tour itself was quite boring. There is a huge expensive art gallery in the building that is open to the public that houses a lot of famous works. But the bulk of our tour was just seeing the power systems… which you can’t really see because they’re just giant pipes. Nonetheless, a conceptually and architecturally very different building that is certainly special when compared to other bland office buildings, but not too exciting from the perspective of a tourist. tldr; cooling system is powered by water from the Vltava, won a lot of awards as an awesome office building, but the visit itself was boring
