The caravanserai was built in the 13th century under the reign of Izzeddin Keykavus II (ruled 1246-1257), Sultan of the Rum-Seldschuken. It is one of numerous caravanserais on the Seljuk trade route from Konya via Aksaray to Kayseri.

The Han is located about east-west and parallel to the former and present street, the entrance is on the east side in the direction of Kayseri. The building measures about 90 m in east-west direction and 60 m in north-south direction. To the east is the richly ornamented portal, which juts out two metres from the outer wall. Through the gate you enter the courtyard, which is adjoined to the west by the main hall.

The building is made of yellow stones, which give the Han its name. At the hall portal and at the roof arches in the hall alternately light and dark stones form decorative patterns. The building was extensively restored in the late 1980s, using the same type of stone as the original building.

Above the portal there is a mosque (mescit) with a fan-shaped dome decorated with muqarnas and a mihrab (prayer niche) in the south wall. On the south side of the courtyard there are open rooms separated by arches, which were probably used as stables.

To the west of the courtyard, another portal leads into the main hall, which measures about 25 × 25 m. It is equipped with a simple central dome and has a central nave and five transepts on each side.

Demonstration of dancing dervishes in the main hall

In the evenings there is a show in the main hall, in the summer also in the inner courtyard, for the numerous mostly foreign tourists of dancing dervishes for more than 45 minutes. In principle, photography is forbidden, but the ban is ignored by many tourists.
