Wat Phra That Chom Ping

Location: 198 Soi Ban To-wang Phrao, Tambon Wang Phrao, Amphoe Ko Kha, Chang Wat Lampang 52130

This place is just made me ask the question "How?" for thousand times! I could not understand how it happens.

Inside there is this place... 

which has this window....

that has this hole...

In front of the window is the pagoda.

Where as when you go inside that structure, close the door and let the sunlight through the hole of that window, you get this...

As to how they did it, I am completely lost! It's a beautiful place to visit and it's very interesting.
