Sultanhan is a large 13th-century Seljuk caravanserai in the town of Sultanhanı, Aksaray Province. It is one of three huge caravanserais in the province, about 40 km (25 miles) west of Aksaray on the road to Konya. The fortified structure was built in 1229 during the reign of the Seljuk sultan Kayqubad I (who reigned between 1220 and 1237) by the Syrian architect Muhammad ibn Khalwan al-Dimashqi (Dimashqi means “from Damascus”) along the Uzun Yolu (or “long road”) trade route, which runs from Konya to Aksaray and continues into Persia.
After it was partially destroyed by fire, Sultanhan was restored and extended in 1278 by the governor Seraceddin Ahmed Kerimeddin bin El Hasan during the reign of Sultan Kaykhusraw III. It became the biggest caravanserai in Turkey and is still one of the best remaining examples of Anatolian Seljuk architecture.
