It is one of the five kızık (twenty-four clans of Oghuz Turks) villages on the slopes of Uludağ, 13 km from Bursa on the Ankara road in the east of Bursa. The 700-year-old historical Cumalıkızık village, one of the rare villages that preserved the Ottoman period housing texture until today, is one of the important examples of Ottoman period rural architecture and still maintains its traditional lifestyle.

Orhan Bey is a residential area established as a foundation village. Cumalıkızık, one of the first regions where the Ottomans settled in Bursa, consists of a total of 270 houses, 180 of which are still used and in some of which conservation and restoration works are carried out.

Generally two or three-storey houses are accessed through the courtyard with a wooden door with two wings from the street. The floor of the courtyard is made of earth or stone. The first floor with low ceilings is the winter part of the house and the second floor with high ceiling is the summer part of the house. Veranda and sofa are directed to climate and landscape. On the ground floors of the houses, the traditional stone material with wooden beams is dominated by adobe material between the wooden roof and the wooden material with crushed roof covered with the Ottoman style tile on the roof. The walls are generally yellow, blue, white, purple and green. There are no windows opening to the outside for privacy on the ground floor of the houses. The windows are located in the empty room.
