Covered section with open courtyard (COC)
Covered section is smaller than the courtyard
Covered section with a central aisle and 2 side aisles on each side
9 cross vaults

The most remarkable features of this structure are the arcaded courtyard, the twin majestic portals of the entry vestibule and the covered section, the vaulting system supported by piers, and the free-standing  kiosk mosque rising on four piers in the middle of the courtyard.  The stone decoration of the mosque and the portals is also noteworthy for its elegance and artistic mastery.

Plan:

The han lies parallel to the road, and faces southwest towards Aksaray.

This Sultan Han is in the group of "classical plan" hans, that is in two parts: a huge enclosed hall on the south and an open courtyard in front of it.  With this han begins the era of the "big" hans: the large-scale construction projects of the hans of Ağzikara, Zazadin, Sultan Han Kayseri, Incir, Susuz, Obruk and Karatay.

The richly carved portal of the han, which projects out from the walls, together with the 6 hexagonal corner towers and the 18 smaller side towers give it the appearance of a fortified castle.  There is a monumental view over the surrounding plains from the roof.  The walls are built of finely-dressed ashlar stone, with the roof also of stone. 

 

Portal:

Entrance to the han is through an imposing portal and a rectangular vestibule covered with a star-shaped vault. The marble portal is 13 m high, projects out about 1.5m and is almost  50m wide. The portal is balanced on each side by a grouping of three columns on the front wall.

The portal has marble carved side panels of interlaced polygons dotted with flowers, a curious combination of a strong geometrical element with a delicate natural motive. A graceful arch with an intersecting ribbon decoration surrounds and crowns the stalactite vault.  There are two columns on each side with a strong zigzag pattern, topped with palmette capitals.  The cursive inscription band runs at the base of the stalactite vault above a band of bicolored marble stones (pale gray and white), like those seen at the Alaeddin Mosque in Konya.

The bicolored marble and the patterns used here are typical of the Syrian-Zengid style that would have been familiar to the Damascene architect. 

The vaulted rooms on the two sides of the entrance vestibule were used as office rooms and for administrative operations.  There was also a 3-room bath group located at the left corner of the entry.

Courtyard:

Along the right-hand (west) side of the courtyard is a decorated colonnade for  storage of goods and stabling of animals.  The high and open vaults facilitated the loading and unloading of goods.

This side of the courtyard also houses latrines grouped together in the large corner space at the northwest corner.  There is a deep stone channel encircling the space on the east, north and west sides.  Apparently there were several individual latrines along the channel, divided by wooden partitions.  

Kiosk mosque:

The mosque of the han is a free-standing structure in the middle of the courtyard, similar to the ones seen at the Kayseri Sultan, Ağzikara and Sahipata Hans.  It is supported by four big arches and contains a mihrab on the inside.  The mosque is approached by a set of steps to the south side.

The power and elegance of the decoration of this kiosque mosque rivals that of the portal, and is worthy of the sultan who probably worshipped here.  The mosque was raised to separate it from the hubbub of animals and goods below, to create a clean place for worship.

Covered section:

The huge hall contained the sleeping and living quarters for the winter months.  The interior is divided into 9 aisles through arcades running east to west and covered with barrel vaults.  There are two rows of confronting arches that flank the central aisle perpendicular to the portal.  This central aisle, which is wider than the others, has the character of a nave.  The central vault of the east-west aisles intersects it to create a section at the center for orientation.  A dome with a conical cap on the outside covers the square unit at the center.  This dome is of technical interest, for it is made of pieces of stone laid helically like a snail's shell, achieved without a mold. There is a handsome carved rope motive at the juncture of the dome with the squinches.

DECORATION

Decorative elements comprise arabesques, blossoms, crescents, braids, trelliswork, Syrian knots, and patterned brickwork in the arches.
