Meteora has been one of the most amazing places I have visited. When you first drive up and start seeing these peaks, you are like "cool" then when you start getting closer and start realizing that there are structures at the tops then you start questioning how is that possible.
As you get closer you begin to wonder how in the world this was done, it is ridiculous how they were able to build these monasteries at the top of these peaks such a long time ago. It had to be aliens!! The monasteries all vary in size, but all have in common the amazingness of unbelievable architecture, intertwined with nature and marvelous engineering.
