Seyfeddin Torumtay had this tomb built in 1278 right across the Mosque of Gök Madrasah. Besides Torumtay himself, the corpses of his children and grandchildren are also entombed in the same structure. The plan and engravings of the tomb is quite different than other Seljuk tombs. This two-storey tomb is built mainly of hewn stones. The broken stones used inside the walls and the brickwork used in the vault is concealed with plaster. The pillars supporting the stairs and the walls protrude from the bearing walls. The engravings mostly observed on and around the doors and windows are seen on the upper part of the building. It is believed that the engravings of the building were left unfinished. There are high reliefs in the upper right and left corners of the southern facade. On this same facade, forming the front side of the building is an ornate window placed in a marble niche. On the pediment of the niche, which is unusually left plain, is the four-line construction epigraph of the tomb. On a second epigraph above the niche itself are verses from the Holy Koran. The pediments of the windows on the eastern and western facades are damaged. There are two entrances to the tomb on the eastern and western facades. The repair epigraph above the window on the inner face of the southern wall shows that the tomb was repaired in 1891-1892. Of the sarcophagi on the lower floor of the tomb, the one belonging to Torumtay is engraved in celi style with verses from the Holy Koran.
