Guess the place (the game)

It's not Caerphilly Castle.

The closest I could come up with was Buckingham palace but I dont think thats in Wales.

Yep, last time I checked, Buckingham Palace was still in England.

Second clue:

Queen Elizabeth II's pet of choice originates from a certain county.

The place in question is also in this county.

So it wasn’t in New South WALES?

Tis this one. Neath Abbey and Gatehouse.

Sorry.

Bishop’s Palace ruins at St David’s in Pembrokeshire, Wales, UK ?
If correct, I’ll skip my turn

Bingo!

Who wants to post a pic next?

Ephesus, Turkey ?
If correct, I’ll skip my turn

yep,
an ancient communal toilet, no need to flush, there was running water under the holes.
Mary, mother of Jesus and the apostle John might have used this as they both lived here.

Durango, Colorado

yep
Durango & Silverton Railroad. great trip

Next up...

I was looking where “Night Passage” (1957, great movie starring James Stewart) railroad scenes were filmed, but the Raccoon shot first !!

Next pic is Château Giscours, Labarde, Gironde, France ? (Edit : a winery in the Margaux appellation of the Bordeaux region of France)

If correct, I’ll skip my turn

Per IMDb…
“Butch Cassidy and the Sundance Kid” and “Breakheart Pass” would be two other movies using the railway.

You nailed it!

Who wants to go next?
