“The canyon of Kanin is located 6 km from the city of Vlora. This fortress was mentioned since the IV century. However, traces have been discovered since the Illyrian period. It is believed that it was built since the III century. The later traces are those of Byzantine, Venetian and Turkish periods. The castle was rebuilt by Justinian in the 5th century and repaired by Sultan Sulejmani in 1531. The castle rises atop a hill with a height of 380 meters above sea level. It has an area of 3.6 hectares. From here opens a beautiful view towards Vlora and its bay.
In the middle of the Vlora bay, high mountains approach to the shore, dividing it into two parts. In this area, slightly drained in the depths, a 379 m high hill is built, where the ruins of an old city, that of Kanin, lie. Here, the valley of the Vlora River is extended to the shadow of the hill, thus facilitating the connection of the coastal area with the hinterland. This is the most important factor, since south the mountains gain high altitude, while with the north the distance between the coast and the valley of the Vlora River rises quite rapidly. These are the conditions that determine the strategic importance of Kanin, as well as the crossing from the southern part to the north (and vice versa), as well as to the connection of the Vlora River Trees with the Gulf of Vlora. On the other hand, the hills around it create good conditions for the development of livestock, while in the east there are quite large and suitable agricultural lands, thus complementing the strategic and economic position.
The above conditions have influenced in this place since the ancient times, to give birth to a fortified center, whose life lasts almost uninterrupted until the last century. Of course, the role of this center has not always been the same, so it has had a first-rate role or has been dependent on other centers in function of the socio-economic conditions of the respective periods. In addition to the strategic and economic conditions, the country also fulfills the other requirements needed for the establishment of a fortified center: communication, drinking water, stone construction and natural protection.
