The caravan saray Tash-Rabat (translated as 'stone fortress') is located in the Naryn region, not far from the border with China. Hidden in the distant Kara-Kayun gorge, at an altitude of 3500 m above sea level, there is a completely unusual and therefore very mysterious monument of medieval architecture in Kyrgyzstan - Tash-Rabat. Historians and archaeologists are still arguing who, when, and most importantly, why built this unusual structure of solid stone in such a sparsely populated area.

Some scholars consider Tash-Rabat a caravanserai of the late Middle Ages, while others suppose that this building is the ruins of a Nestorian Christian monastery. Along with significant differences, buildings very often had common features, both architectural and functional. After all, it is no secret to anyone that monasteries never refused overnight accommodation to merchants, and pilgrim monks were very warmly welcomed in caravanserais.

This is a carefully restored stone building, which once housed an inn on the Great Silk Road. The date of its appearance has not been precisely established, but archaeological facts suggest that this place was already occupied as early as the 10th century. 15 km higher, at the foot of the Tien Shan, there is a beautiful valley nestled on the mountainside. There is evidence that it was a place of both rest and worship, and it was also used to protect caravans heading to and from China from violent weather and robbers even before the time of Tamerlane and Genghis Khan.
