At the Caravanserai HWW

In the mountains of Kyrgyzstan on the Silk Route heading from China, the huge remains of a fifteenth century caravanserai still stand. A safe haven against robbers, wild tribespeople and villains, traders took their caravans of pack animals into the safety of these thick stone walls, and stayed within the chambers inside.
Also protection against the bitter night cold at these altitudes.
