Gjirokastra, in the Drinos river valley in southern Albania, features a series of outstanding two-story houses which were developed in the 17th century. The town also retains a bazaar, an 18th-century mosque and two churches of the same period. These two fortified historic centres are remarkably well preserved, and this is particularly true of their vernacular buildings. They have been continuously inhabited from ancient times down to the present day. Situated in the Balkans, in Southern Albania, and close to each other, they bear witness to the wealth and diversity of the urban and architectural heritage of this region. Gjirokastra was built by major landowners. Around the ancient 13th century citadel, the town has houses with turrets (the Turkish kule ) which are characteristic of the Balkans region. Gjirokastra contains several remarkable examples of houses of this type, which date from the 17th century, but also more elaborate examples dating from the early 19th century.The town of Gjirokastra bears outstanding testimony to various types of monument and vernacular urban housing during the Classical Ottoman period, in continuity with the various Medieval cultures which preceded it, and in a state of peaceful coexistence with a large Christian minority. Berat and Gjirokastra bear witness to a way of life which has been influenced over a long period by the traditions of Islam during the Ottoman period, while at the same time incorporating more ancient influences. This way of life has respected Orthodox Christian traditions which have thus been able to continue their spiritual and cultural development. The city in the south of Albania was elected UNESCO world cultural heritage. Reason for this is the unique architectural style, most of the buildings show. The style is called Balkan architecture and contains small castle-like houses made of stone. The stones should control the temperature in ancient times and today form the town’s landmark. Therefore the city is also called “city of stones”. It is located at the side of a hill and the single quarters are connected with artistic roads.
