I was reading up one the wonders of the world the other day. I didn't know there's actually a various list of the wonder world. It is actually a very good read if you have no idea which are the wonder world.
Wonders of the World have been compiled over the ages to catalogue the most spectacular constructions and natural things in the world.
PS// The above image is blue mosque, it got nothing to do with the wonder world. Still, don't you think its jaws dropping?
