Material deteriorations occurring on the facades of the Mor Sergios Bakhos Church

Abstract

Mor Sergios Bakhos Church is an important monument having significant tangible and
intangible cultural heritage value regarding the geographical context, where it is located.
However, various material problems have occurred on the stone structure as a result of
various conditions today and the structure encountered the risk of being destroyed.
Within this context, the aim of the study is to determine and document the material
deteriorations of Mor Sergios Bakhos Church, which is one of the symbolic values for the
city of Mardin. Ground laser scanning technique was used in order to achieve this
purpose and orthophotographs were obtained from the point cloud data via the various
programmes. Facade drawings of the building were achieved with the help of the scaled
orthophotographs obtained. In the final stage, material deterioration schedules were
processed on the facade drawings obtained and the damage maps of the building were
obtained. Most frequent material deterioration seen on the facades of the building is the
use of cement and paint arising from the faulty repairs, according to the findings. Within
this context, it was concluded that preventing the human-originated faulty repairs, which
was the greatest problem seen on the building, is important within the context of
ensuring sustainability.
