With the ones that I have answered, I located them by using keywords that describe the image in a Google image search. It was just a case of finding the right words :)

For example for http://cellar.org/showpost.php?p=777292&postcount=574 I used "Golden Tree France" (I guessed it would likely be in France)

For http://cellar.org/showpost.php?p=778581&postcount=668 it was more difficult to find the right words. Most searches using words such as caves, cliffs, rock face, dwellings came back to Petra. Knowing that many such places have a religious significance, I added religions to the searches. I can't remember exactly what I used but it was something like "caves Buddhist" that led to the answer.

For http://cellar.org/showpost.php?p=778786&postcount=678 I used 3 words that described the picture and the answer came up straight away. Those 3 words are...

That's the trick. The skill is in observing what's in the picture. Your knowledge helps with that, but sometimes it's just plain observation. If you know enough that a particular church has a Russian Orthodox look to it, then that's going to narrow your search down considerably.

But then other times your knowledge hurts you. Like if you are looking for totem poles in the Pacific when the pole is really in Delaware.

You guys are killing me. I want my 45 minutes back. This game is deadly.

By the way, I got next.

I can't tell if 678 has been answered yet or not. :right:

Not.

I know! I hate it, but I love it.

Notre-Dame-du-Haut (Ronchamp, Franche-Comte)?

The 3 words I used to find it were "church modern architecture"

I used 4: modernist open air chapel

Yes!

You could also use white concrete church
