Cemilli Castle (Turkish: Cemilli Kalesi, also called Kaleburnu Castle) is a medieval castle (or an observation tower) in the rural area of Mersin in southern Turkey.
Both Cemilli and Kaleburnu are Turkish names. The original name of the castle is not known. It is a small medieval age castle. It was built probably to control the road to north. Presently most of the building has been demolished. There are cracked pieces of ceramic coating from the Byzantine, Seljuk and Ottoman eras around the castle.[1]
