Creation of the constitutional monarchy?
Not that. I’ll give a further hint - it’s not (usually) political that I’m aware of.
First modern Olympics!
I am thinking of a place…
Is it on Earth?
Yes.
Is it in the Northern Hemisphere?
It is.
Is it in Europe?
Is it a town/city/village?
Yes to both, although there are a few places across the world (and a few not in this world) that share its name.
Is it a country where English is a commonly-used or native language? (trying to narrow it down.)
Is it important in a world religion?
The place I am thinking of is not in a majority English speaking country (although I am willing to be corrected). However, there IS a place of the same name in a majority English speaking country.
The physical place on Earth isn’t important to a major religious movement to my knowledge. However, this place in general IS very important in at least one major religious movement.
Is it Heaven?
I’m sure there are plenty of places called that
The physical heaven isn’t that important, the abstract one is
It isn’t Heaven but…
Hell?
Yes, but which particular Hell?
The Norwegian one?
