Turkish expedition Ankara castle is located on the old city hill, with well-preserved thick walls and charming streets overlooking Ankara panoramic views. It was built by the ancient Romans in the 2nd century BC for military defense. The roads here are intricate and the ruins are full of historical vicissitudes. Because it is located in a strategic location, the castle has been baptized by the war and has been captured by Byzantine, Persian, and Arabs, so there are not many castle buildings left. Today, it has a face.
