The magnificent and luxurious Divan-Khana was built from eight-pointed rotundas on a high throne, surrounded by arched balconies from five sides. The entrance portal of the Divan-Khana is rich in complex ornamental patterns engraved on the stone, and decorations similar to the delicate weaving are laid and the leaves from Azerbaijani flora are depicted on the right and left sides of the entrance. The verses of Islam are engraved in ancient Kufic writing on the 6-point trays placed on the portal frame from both sides. On the left tray, the words " There is no god but Allah, Mohammad (saw) is the messenger of Allah, Ali (a.s) is the wali of Allah," and on the right tray, the words "Allah is the only One” “Muhammad" are written.
