If you don’t know what a caravanserai is, let me explain. Back in the days when travelers used the Silk Road to come to his destination with goods or whatever, they had these staging posts so the traveler could rest. Without the posts the traveler wouldn’t make it through the desert. There were thousands of them in Asia, Africa and parts of Europe, but today they are dusting away. The caravanserais are usually built in a rectangular shape with a walled exterior, and they had very wide doors so travelers with camels could come in and rest from the long travels.
