Divrigi Great Mosque - High 1;
The architect was Hürremshah of Ahlat and the mosque was built on the order of Ahmet Shah, ruler of the Mengujekids.The inscriptions contain words of praise to the Anatolian Seljuk sultan Alaeddin Keykubad I. The adjoining medical center (darüşşifa) was built simultaneously with the mosque on the order of Turan Melek Sultan, daughter of the Mengujek ruler of Erzincan, Fahreddin Behram Shah.
The exquisite carvings and architecture of both buildings put them among the most important works of architecture in Anatolia and led to their inclusion on UNESCO's World Heritage List in 1985. Of particular note are the geometrical and floral reliefs on the main door.
