Mar Petyun Keldani Church

Mar Petyun Keldani Church is a historic church located in the Özdemir Neighborhood of the Sur District in Diyarbakır, near the Şeyh Mutahhar Camii. This structure, still actively used by the Chaldean Catholics, has an uncertain construction date. Due to insufficient written records and the absence of an original inscription on the building, its founding date has not been definitively established. However, an inscription dated 1834 above the entrance in the northwest corner is generally accepted as marking a renovation date. It is known that the building has undergone multiple repairs throughout its history.

Like many structures in Diyarbakır, Mar Petyun Church is constructed primarily of black basalt stone. Its plan consists of a three-nave layout divided by arches and five apses. The church’s basalt stone walls harmonize with the baklava-slice and two-colored stone pavements in front of the apses. In addition to volcanic basalt stone, materials such as earth, wood and lime mortar (cas) were also used in its construction. Block stone was preferred for walls and pavements, lime mortar for decorative elements, and wood for furnishings. Iron is also notable for its functional use in the bellies of arches for hanging lamps and in window grilles.

The church forms a complex structure with interconnected auxiliary buildings. In addition to Mar Petyun Church, this complex includes a residence and three courtyards. The complex is arranged in an irregular U-shape around the courtyards.

According to some sources, the origins of Mar Petyun Keldani Church date back to the 17th century. However, this date has not been confirmed by definitive written documentation. The Chaldeans are one of the communities that have maintained a presence in the Diyarbakır region for many years, and today a small number of Chaldean families continue to use the church for worship, liturgical ceremonies and weddings. The church also functions as an art gallery and is one of the few active churches in Diyarbakır today.
