This architectural complex in Turkey from the medieval period was established by Chief Ahmet Shah of the Mengücek dynasty between 1228 and 1229 in Eastern Anatolia, within the Divriği mountains.
The Great Mosque and the adjacent mental hospital (Marestan) were both designed by the same architect, Khurramshad d’Ahlat. The only prayer room in the mosque features five vaulted stone ceilings, showcasing remarkable craftsmanship and an astonishing spatial arrangement. Above the prayer room are two domes of different sizes, one dome positioned over the baptismal font and the main dome placed above the Mihrab (the decorated wall niche indicating the direction of Mecca). The tower atop this dome is the most refined architectural element of the mosque.
The walls surrounding Divriği have three splendidly decorated gates, featuring floral and geometric motifs reminiscent of contemporary Armenian and Georgian designs. This complex was inscribed on the UNESCO World Heritage List in 1985.
