Only recently scientists found ruins of the majestic caravanserai. Nowadays here it is possible to see the huge Portal located on following from Bukhara to Samarkand. This road trade caravans in the Great Silk Way. The Portal has been decorated by a brick which created a pattern from 8-faced figures and 3-leaf type figures. Contours of the Portal were decorated by art painting.
Only a part of the southern facade with a tower has reached our days, but about planning of fortress it is possible to judge by results of excavation. Fortress represented a rectangular construction with the party in 100 meters where on each corners there were 15 meters high towers. Outside of a wall of fortress are decorated with the flat semi-columns grouped in pairs.
The entrance to strengthening was one — through the remained southern portal. The portal acts from a wall a little, it is rectangle type in the plan is cut through by a lancet arch and decorated with a brick ornament. From the Portal the gallery isolated from the rooms which were in the southern part deep into conducts (housing for servants, stables, kitchens with tandoors). The gallery conducts in an octagonal rotunda in which arches, as well as all galleries, were trimmed carved plaster with clay using. From the rotunda serving as the central hall, the courses conduct in a northern inhabited part of a complex. In the middle of a complex at an entrance to a northern part there was a small mosque with Mihrab on the western wall and a Minbar at the left. Walls and a Minbar have been decorated carved plaster with blue sub paint. A set of human bones have been found in excavation that demonstrates that there also was a cemetery area.
Today historians can say with a certain confidence that this portal belonged to one of the most large-scale Caravanserais in the region which carried the name Rabat-i Malik (“the Gate of Bukhara”). Using of the remained drawings of the Austrian traveler Alexander Lehmann in 1841 — 1842, allowed architects to recreate its shape almost completely.
