The remains of this ancient fortress overlooking the city center can be reached by a trail that winds up from Gölbasi Park.
The hill is known by locals as Nimrud Kürsesi (Nimrod's Pulpit), and whole colonies of hermit ibises nest on the steep rock faces.
A 12-meter manmade ditch separates the castle from the hinterland. The castle's age is not known, but local lore states that this is where the Prophet Abraham's funerary pyre was built by King Nimrod.
