An excavation was performed during the 2008 campaign in an area of 40.00 x 35.00 m called “Kasır” located to the south of Koç Mosque and to the southeast of Hasankeyf District. Excavation work was initiated by preparing 5.00 x 5.00 m grid-squares in the area.
A stratification consisting of rubbles and fillings was observed inside the trench G4 on the southeastern part of the excavation area as it has been used as a waste disposal site of the quarter. Trench opening was initiated by removal of waste and fillings down to a depth of 0.60 m. Gradual excavations yielded several structures.
It appears that the structures in the Kasır-1 excavation area have been damaged to a great extent. Significant conclusions were reached in terms of having an idea about formation of the urban texture as a representative of the civil architecture and in terms of documentation. It has been documented that following the abandonment of the quarter, the cover and walls of the buildings were dismantled, and the architectural texture was destroyed to the foundation level. It was observed that the walls which have been destroyed without leaving any architectural clue belong to different periods. While more regular wall remains plastered with cas mortar were found in the lower layer, there are poor quality walls from late period consisting of rubble stones laid in mud mortar on the upper layers .
The excavations revealed presence of a street fabric with partially uncovered floor stones and dwellings on this street to the north of the area, however the original form of these structures has been altered since the area was dominated by various people several times . Yet these excavations helped documentation of the architecture in the Yamaç Quarter that extends up to the bedrock to the south of Hasankeyf along with Yamaç-2 and Yamaç-3 buildings that were unearthed in 2005.
The Manor House–1 area was rich in pottery finds. The sherds of red paste ware from local shops were transferred to the excavation house for analysis. In addition, there were three imitations of white paste İznik ware among these sherds (Image ). Also found are three glazed bricks and two meerschaum pipes.
