[2] The Sangachal caravanserai is located on the shore of the Caspian Sea bay, and the small river Dzheyrankechmez with fresh waters which flows on its left side.
[6][7] The external appearance of the caravanserai is determined by a regular rectangle of straight walls, built of purely hewn large limestone stone.
The presence of semi-circular towers, decorative elements on the outer walls and peculiar windows makes the Sangachal caravanserai look like a defensive structure.
The volumetric composition is based on contrasting techniques when the emphasized facade of the central part and the developed form of the entrance are opposed by low clumps of walls with angular axial towers along the perimeter.
[8] The entrance is arranged in a rather original way: between two small rooms in the lower tier of the portal, there is a deep opening covered with a lancet vault, which leads to the courtyard.
At the top of the central volume of the main facade there was a balakhane - three small rooms, to which open stairs that led from the courtyard.
Underground catchments of a rather large volume, covered with lancet arches and intended for capturing and storing subsoil spring waters, are located at a relatively great depth from the surface of the earth.
Small but expressive volumes of ovdans with emphasized pointed arches of portals interacted with the architectural forms of the caravanserai, creating a single volumetric-spatial environment.
Fatullayev, “the caravanserai in Sangachal is a period of formation and development of civil structures at a new stage of understanding the stylistic features of Absheron architecture, which laid the foundation for the construction of many buildings of this type.” The "attachment" of the continental Asias trade infrastructure to servicing long-distance caravan trade led to the destruction of the Silk Road leading to the decline of this infrastructure as well.
But, according to researchers, the Sangachal caravanserai was not abandoned: small traces of repair and restoration work and reconstruction indicate that the building functioned for a long time.
In 2008, at the international conference Strabos Way as part of the Great Silk Road, held under the auspices of the International Institute for Central Asian Studies of UNESCO, the Doctor of Philosophy in History, the Associate Professor Sabuhi Ahmedov read a report on the topic Museum Azerbaijan on the Great Silk Road in the caravanserai Sangachal.
