Tash-Rabat was constructed in the 15th century, on the ancient trade route from Central Asia to China, and was a resting place for merchants, ambassadors, travelers and other wanderers. It is the largest structure built of stone from Central Asian architecture of that epoch. It is notable not only for it's size and building materials, but also for its special layout, based on perfect symmetry. Lost among the primeval wilderness, far from inhabited locations, the caravanserai looks unbleached, monumental and unassailable.
This is a carefully restored stone building that once housed an inn on the Great Silk Road. Its date of origin is a complete mystery; however, there is archaeological evidence to suggest that the site was occupied in the 10th century. Set some 15km up a small, beautiful valley in the foothills of the Tian Shan, the whole structure is embedded in a hillside. There is evidence that it was a place of both rest and worship and would have served to protect caravans traveling to and from China from both the ravages of the weather and of bandits; even before the time of both Tamerlane or Genghis Khan.
