İn further north of the Altıntepe Necropolis, there is a Kalecik Necropolis area and all of the underground carved graves in this area have been robbed by treasure hunters. The graves in this area were opened to a soft calcareous layer as in Altıntepe. The burial chambers, which are deeper than the well-shaped dromos, can be reached with a few steps. The entrance to the chamber grave was covered with flat flag stones. The sizes of Kalecik graves vary between 4.50x2.40 m and 1.80x2.90 m. The niches were also applied to the side walls. In smaller burial chambers niche openings are not found. Grave chambers are generally rectangular or square plans with rounded edges and some of them have terrace. There are also examples that do not present a particular shape. The heights of the burial chambers are not very high (1.30 meters). In the K24 Burial Chamber, three niches were applied in three direction and 10 niches were opened on the side walls. In the K25 Grave, there are four terraces application and 12 arched niches were opened to the walls of these graves. There is not much data on the burial tradition as all the graves have been robbed. However, 8 skulls and skeleton remains were found in-situ in the eastern part of the northern wall of the K3 Tomb. The collection of skulls in certain areas is also encountered in the graves of Karagündüz and Yoncatepe.
