In Western Germany, this never came up anywhere and it also wasn't a major part of history education or things like that.

I've still never been there.

And when the UNESCO thing came up, I had to refresh my knowledge to differentiate the French "Sun King" Louis from the Bavarian king who ordered the building of this castle.

My first introduction to it was that it's a place where foreigners like to go and a popular tourist attraction.

No sure why this incited so many downvotes, but nevermind.

I think it's a common phenomenon with "trademark" things that countries are known for around the world.

This is particularly extreme because it's very specific to Bavaria.

There are many castles in Germany, most of them older than this famous one. Lots of castles in my vicinity too, although they're not as famous.

That's weird though, executive charges are elected representatives as well for the whole jurisdiction. Legislative charges are representatives of specific sub jurisdictions (counties at state level, states at the federal level)
