Sultan Han is a historic Seljuk-era caravanserai in Turkey, located 47 km northeast of Kayseri on the road to Sivas, in an area also known as Tuzhisar.
[4][2] Like other Seljuk caravanserais, it served as a stop for travelers and merchants along the major trade routes of the region, providing lodging and other basic services.
Its exterior has a fortified appearance and the entrance is marked by a monumental portal with rich stone-carved decoration including a vaulted canopy of muqarnas.
Opposite the entrance, at the other end of the courtyard, is another portal which leads to the "winter hall": a main vaulted nave with a central dome (marked by a conical roof on the outside), from which other vaulted chambers open on either side.
[2][4][1] The building also contains notable examples of Seljuk stone-carved animal motifs, including drain spouts resembling lion heads and serpentine dragon motifs along the lower arches of the elevated mosque in the courtyard.
