The best information I could find was, translated "Built during the period of the Danişmentliler, the Gülük Complex consists of a mosque madrasa and a hammam, which is located next to them and is not available today.

There is no inscription indicating the construction date and the builder of the complex or mosque. The older of the two inscriptions on the building is on the portal on the northeast facade and added later. According to this inscription, the buildings were repaired in 1211 by Atsız Elti Hatun, the daughter of Yağıbasan Mahmut, the nephew of Sultan Mehmet Melik Gazi. This inscription on the portal consists of three lines, and the Turkish inscription written with the Seljuk sulcus is as follows: "This building is the son of Keyhüsrev, the honor of the world and religion, the owner of conquests, the partner of the Emir of the Believers, during the reign of the great Sultan Keykavus, Atsuz Elti Hatun, the weakest servant, chaste woman, daughter of Mahmud, son of Yağıbasan, had it repaired in 607 (1210). " Damaged by the earthquake in 1334, the building was repaired for the second time in 1335 by Alemuddin's son Külek. "

It has a simple interior with a mihrab that is tiled and was added later. I had the strong impresion some parts, even some fragments, were added later again.
