There is a Wikipedia List (German) [1] of quite a few of those (in Germany and in other countries). I stumbled upon it, while trying to find a link to the one in my home town I have wandered quite a few times, as I lived between Neptun and Pluto (it was built before Pluto was demoted), very close to Pluto. It ran the street I grew up in and was built to scale (1:4 bln scale) by a teacher who was a full blown astro nerd and in his free time taught quite a few of the local youth about space, planets, the science behind it, but also built rockets with us and let them fly.
I so fondly remember him, as he was one of those people being a massive inspiration to my life.
That looks really cool! I've visited scale models of the solar system in Eugene, Oregon[1] and Norwich, Vermont[2], but neither one is anywhere near that size.
