Domestic travel in Uzbekistan.

"The secrets of life that I have set out in the secret book,
I hid from people for my safety.
I can not tell anyone what I hide in the shower
Too many ignoramuses in this evil human herd. ”

Omar Khayyam.

Shichrisabz Tour.

The Koba caravanserai of the XVIth century are an important part of Central Asian civil architecture. They are based around a courtyard rectangular with indented corners. The Koba caravanserai in Shakhrisabz is the only monument of its kind in XVIth century architecture.
Other caravanserais of the city have not been preserved. The Koba caravanserai by its typology refers to a one-yard, one-storied building with the buildings located along the perimeter of the courtyard.
Unlike similar buildings in Samarkand or Bukhara, Koba, constructed in the XVIth century, has a more modest architectural appearance. The entrance portal conventionally faces the historical main road of the old-town part of Shakhrisabz.
The form of the courtyard is nearly square with chamfered corners of less than 45 degrees. Khudzhras are covered by vaults of a pointed profile. The lack of external decoration, the thickened walls, the courtyard with chamfered corners all suggest that the caravanserai does indeed date from the XVIth century.
According to stories passed down from generation to generation, merchants from different countries including India used to stay in this caravanserai. There are several theories as to the origin of the name 'Koba.
Some locals believe it comes from the word 'Kuba' (dome); others that it is a variant of the word 'Kufa', suggesting that it was constructed by masters from the Arabian city of Kufa.
