Çukur Han
Çukur Han is a historic caravanserai located in the Atpazarı area of Ankara's Altındağ district. It is situated near the main entrance gate of Ankara Castle, to the northwest of Çengel Han. It is known to have been endowed by Ankaravi Mehmet Emin Efendi, the Sheikh al-Islam of the period, along with several other structures such as Suluhan. Çukur Han, whose construction year is dated between the 16th and 17th centuries, underwent two major renovations in 1791 and 1801. By the 2000s, due to both its long disuse and the lack of significant reinforcement work, it was listed by the World Monuments Fund as a structure "in urgent need of rescue."
