Actually, on second thoughts, given the ABSTRACT primary definition, I wonder - Is the answer the name of a geographical area in some sense?

best known for event? Um, I am not sure if it is known for anything
in EU? Yes.
Name of town (hamlet/city, etc.)? No, unless "etc." is very broadly defined.
beauty of nature? Er, I have no idea, really. I'll hazard a guess at yes, though I don't think it is particularly known for its natural beauty.

Ah ... good thing I previewed before posting. Name of a geographical area? Yes. *applause*

France? No. 24 to go.

Oops - forget that one - how about In a country with a Mediterranean coastline?

In current EU? Er, yes. Didn't I already answer that?

Ah, you are saved by the preview again.
Mediterranean coastline? No.

And, for free, here is an addendum to a previous answer. The name of a town/hamlet/city is one of the words on the card, although the answer is not the name of a town/hamlet/city.

Coastline? I am pretty certain that the answer is no.
Administrative area? Yes. *applause*
Scandinavia including Baltics? Yes.

(Make that 99.9% certain that it does not have a coastline)

Finland? No.

Does the name itself consist of more than word? (Or, contrariwise, is the phrase on the card 'the province/region/whatever of ...' plus just one word?)

Oops, missed that it's Scandinavia.

Remember guys - the initial setting said that we've probably never heard of this.

Jonkoping? No.
Form of answer? The answer is two words: Place Name + Administrative Area Designation.
Part of the Third Reich? No.
Denmark? No.
Tivoli Gardens? Never heard of them
In Baltic States? Yes.
Connection to Norse legends? Not as far as I am aware.
Sweden? No.
