The place is called Tintern.

It's being described as "in the Wye Valley", but that's not part of the name.

I don't see how "King's Rocks" (Tintern) is more weird than, say, "Gathering Place By The Water" (Milwaukee)...

I think you guys are taking "weird" a bit too literally, I don't mean it in a negative way.

If it was common here in Canada then I wouldn't find it 'weird' or unusual would I? And I can assure you it's not very common. Even if there are exceptions.

Regardless that was not what the Brits (or whichever Euro empire) chose to eventually name Milwaukee, they chose Milwaukee. So that's a poor counterpoint...

I chose that example precisely because both of them are in the language of the former natives, now barely spoken in the area, and not in the language of the empire that conquered it. ;)

In the US, specifying the state seems to serve the same purpose of avoiding confusion. "Springfield, MA" and "Springfield, IL", as opposed to "Springfield-upon-Connecticut" and "Springfield-on-the-Lake".
