İt is an architectural monument of Middle Ages situated near the village of Gulustan in Julfa region. It was built by the effect of Momuna Khatun tomb at the beginning of XII century. Gulustan tomb (mentioned as “Kesik Gunbez” in Medieval sources) has a special place among other Medieval architectural monuments of Azerbaijan as it differs from them in its architecture-constructive structure.
The vault of Gulustan tomb is situated on the surface part which is called platform. The platform has a shape of frustum-pyramid from outside, but the cylinder from inside. The frustum-pyramid which is like a square in plan turns to a Dodecagon upwards. There is an upper chamber with twelve sides on it. The tomb surfaces were decorated with carved geometric ornaments and decorative arches. As in other tombs of Nakhchivan architectural school, the inside of niches of Gulustan tomb is covered with delicate geometric ornaments. The architect has placed the various formed geometric ornaments on the surface of the tomb so that when one looks at one side, he can see different ornaments on adjacent sides.
The tombs built with the same architectural method of Gulustan tomb are widespread not only in the regions of Azerbaijan, but also in the Anadolu region of Turkey. Gulustan tomb has also a link with the other monuments situated in the surrounding areas. The monuments around the tomb are included in one archeological complex. The architectural style of the tomb is like the monuments of the Seljuk’s period, but the geometric ornaments are like the monuments of Ajami architectural school. Considering the historical and cultural importance of the area where the tomb and monument is located, “Gulustan” Historical-Cultural Reserve was established here. The reserve is situated on the left bank of Araz River.
Gulustan tomb was restored according to the decree “On restoration and investigation of Gulustan tomb” signed by the Chairman of Supreme Assembly of Nakhchivan Autonomous Republic, on October 7, 2015.
