Just this June I've visited the caravanserai in Tash Rabat, Kyrgyzstan. A beautiful and somewhat baffling structure in a sweeping mountainous setting, with just a few yurts beside it to host visitors.

(Highly recommend a visit to and jeep tour through Kyrgyzstan: the landscape is stunning, and the people extraordinarily friendly and welcoming.)
