No trace of the caravanserai survives, but we can reconstitute it based on similar buildings elsewhere. There would have been an imposing gateway leading to a large open rectangular court, whose size depended on the needs of local trade. Some caravans could consist of 20,000 camels but the volume of trade in this part of the world required far fewer animals. Wells supplied water for animals and humans, while a two-story building surrounded the courtyard. There were stables and storage space for the merchandise on the ground floor, while the travellers spent the night in rooms on the first floor. The windowless walls provided the caravanserai with a fortress-like appearance.
