 The name of the chief architect is inscribed in the interior of both the mosque and the hospital and has been read as Khurramshāh b. Mughīth al-Khilātī.The name indicates his origin in the city of Ahlat, known in the medieval sources as al-Khilāt.The exquisite carvings and architecture of both buildings place them among the most important works of architecture in Anatolia and led to their inclusion on UNESCO's World Heritage List in 1985.
