كيقباد الأول
A caravanserai built by Sa’d al-Din Köpek during 1235-1237 survives about from Konya on the road to Aksaray. Known as "Zazadin Han", the caravanserai bears two inscriptions: one naming Köpek as founder and dated 1235–36, the other indicating the patronage of both Kayqubad I and Kaykhusraw II.
