Fun search challenge

Wednesday search challenge (6/27/12): Do you have X-ray vision?:

Since so many people seemed to enjoy a difficult task, today I’m going to ask if you can develop X-ray vision with this image.

I took this picture while on a recent trip somewhere in the world.  The question for today is simple—look through the façade of this building and tell me….

Question:  What kind of trees are planted in the courtyard behind the entrance to this building?

Tomorrow I’ll reveal how I found the answer.  

For extra credit:  What date were trees of this kind first planted?   

As usual, please tell us HOW you found the answer and HOW LONG it took you to find it!  

Search on!
