If you ever come to Sweden there is an interesting model of our solar system here, it covers the whole country. They started to build this model in late 1990s and my teacher in astronomy prof Gösta Gahm was one of them who started this project.
In May 2019 I was invited by Gösta to participate of the installation of Jupiter version 2 at Sky City in Stockholm. I took som photos and did a report from that event. If you find it interesting to read you find it here:

There are of course a lot of other interesting things to visit and see in Sweden!
