The mosque has 3 entrances as the
Kiblah door (north portal),
Market door (west portal), which is the westward exit door and the Shah Portal, located at the east side.
There are four epigraphs providing dates names, four master signatures and 21 boards where basmala, verse and prayers are inscribed in the mosque.
Nine natural and cultural assets are included in the “World cultural Heritage List” conducted within the scope of UNESCO’s conservation efforts. Divrigi Great Mosque and Hospital, with its unique architecture, aesthetic, cultural and universal values and also as a monument symbolizing equality of women and men in the 13th century, was deemed worthy to be included in this list in the year 1985.
Due is other natural and cultural assets included in the World Cultural Heritage list being archaeological sites, Divrigi Great Mosque and Hospital is unique since it’s a monument.
The monument, which was placed on UNESCO’s World Natural and Cultutral inheritance List in 1985, is a structure composed of the Ahmed Shah Great Mosque and Turan Melik Darussifa (house of healing) next to it. According to the inscriptions, the foundation of the kulliye (complex) was laid in December 1228.
The foundation charter prepared for the Mosque is dated to the 5th of July, 1243. These dates indicate that it took 14.5 years from the start of its construction for the kulliye to be opened to worship.
Darussifa mausoleum, nearby hammam and fountain around it give the structure the quality of a kulliye. Parts of the kulliye, like the soup kitchen (imaret), buke (guest house) , palace, open-air prayer area, well and public fountain, which were made of weaker materials, have collapsed.
The portal of the mosque at a height of 14.5 m, of darussifa at a height of 14 m. and the conical hats on the roofs forms are perpendicular.
On the other hand the horizontal situation of the building creates a dominant monumental opposition. Here what is modeled is the territory itself., the traveler moving in the Anatolian steppe which gives the impression of pointlessness and endlessness suddenly either finds himself in the valleys which lie curled at the bottom of steep rocky hills or paexes, or witnesses the gorgeousness of the approaching high mountains. The shadowy hollownessses of the caves and holes are places for a rest. Similarly, the naked walls of Divrigi kulliye ascend like a rock mass, while the conical hats resemble sharp hills, and the huge portals are like the entrance of caves.
The mosque has one portal on each façade, whereas Darussifa has only one portal. The decorated north portal is more glorious and striking than the other portals. This could be explained by the fact that this gate is the main entrance and ceremonial portal.
Ahmed Shah Great Mosque
The mosque side of the Kulliye includes a nave and four aisles identified by the column series. At the center of the nave, which is larger than the aisles, there is a lantern dome whose middle was originally open, but was later closed. The part below could be regarded as a synthesis of the Iran mosque with open courtyard and four iwans, and Anatolia transept-basilica. Therefore, it is a unique creation peculiar to the Seljuk period. The so called ‘maqsura dome’ i.e. the dome before the mihrab, belongs to the early period of mosque architecture, first appeared in Isfahan Great Mosque. However, it is covered by a canonical hat peculiar to Anatolia. In addition to these two covering systems, 23 decorative cross-vaults constructed from stone, are the most sumptuous sample of their kind in Anatolia. At the center of the vaults, the decorative lines cross one within the other and seem like a cross. They give the four cardinal and intermediary directions and the sun or sky gate in the center. Entire vault design is based on the movement of the sun in sky which completes a cycle around the earth through seasons.
Turan Melik Darussifa
Darussifa, which lies adjacent to the south of the Mosque, is the only building with a definition of ‘darussifa’ present in its inscription in Anatolia. The kulliye’s original foundation charter is lost. Therefore, the main reason behind the construction of darussifa is not fully understood. The word Darussifa was used in the 13th century with a meaning of madrasah, imaret of guesthouse. Traveler physicians or surgeons stopped by these buildings and examined the patients. The function of the darussifa in Divrigi was that of ‘guest house’. The place with a central sofa on the upper level of the building could have been used as an official area (divanhana). Ahmed Shah and Turan Melik’s residence for receptions. With the pool at the center of the Darussifa and the dome above it with its hole in the middle, the idea of closed courtyard is emphasized. The three iwans remind one of the idea of the courtyard with iwans in Iran.: the application of four columns s reminiscent of the four-columned Anatolian basilica, the dome application reminds one of a basilica with both with a transpept and a dome, and the corridor application in front of theiwans behind the columns echoes that of basilicas with two aisles and a nave. A unique and inimitable synthesis was made out of the combination of these.
