It covers the inner side of the southern fortification wall of Kale. It is east of tower no. 10 and is 23 m long and 5 m wide.
The archaeological excavations started on 20 March 2005, and they already reached the depth of 5 m on the whole area.
In the course of the excavations, this sector produced a big number of movable archaeological material. The most numerous is the Ottoman and Byzantine period pottery, and there is a significant number of bronze coins – around 120 of the same period. Some of the most attractive movable finds are the metal cross (alloy – pendant) from XV-XVI century, which is a graphic form of a Greek cross with small leaf-like expansions at the edges.
The lead seal with Greek letters inscriptions on both sides is also an interesting find.
No significant finds of hard constructions of the Middle Ages are found on this sector. Most probably this is a free space, some kind of a communication, but there is stone relief, Ionic capital fragment, fragments of marble plate with floral ornaments and a marble pillar basis, which suggests the existence of a more representative sacral facility somewhere near by.
