Someday we will have to show these commemorations in a commemoration of the UNESCO headquarters.
Neuschwanstein was built in the 1880s, at which point any fortification that could have fulfilled its military role you would not want to live in, thanks to improvements in artillery. Castles are functionally obsolete around the 15th century, when gunpowder-based artillery became common and you needed substantial more earthworks and enveloping lines of fire rather than the straight curtain wall you see with castles.
Neuschwanstein is instead a 19th-century version of the McMansion: it's a house (palace, really), built to (then-) modern standards that is dressed up to look like some sort of fancy architecture, in this case, a Medieval castle based not on historical research but in the (then-) modern pop culture version of it.
They're in no short supply even today.

It has a moat and a dungeon in case anyone's interest.
But sure, that's to be expected and the "cultural heritage" designation is not a ranking of the most popular landmarks, for good reasons.
I bet most will have, though.
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.
