Glass is a transparent and fragile building material that is often preferred with traditional materials in restorations. In this study, it is aimed to determine the architectural compatibility of the glass used in the restoration of historical buildings and to reveal the advantages and disadvantages. In this context, Kızlar Monastery, which is located Trabzon in Turkey, has been discussed. The study consists of three stages. In the first stage, the theoretical infrastructure for the subject was created through literature research. The data related to the study area were obtained in the second stage, and the current situation features were examined. In the third stage, glass usage areas were analyzed in the re-using process in Kızlar Monastery. In the findings of the study, it was seen that the interventions made for Kızlar Monastery to connect the past and the future of the building greatly contributed to the original value of the building. As a result, it has been determined that the interventions made by paying attention to the preservation of the original space flow of historical buildings contribute to the sustainability of the values of the building. Keywords: Historical Building; Reuse; Restoration; Glass Technology; Kızlar Monastery Introduction Historical buildings are one of the most important components of cultural heritage. Our social identity is shaped by monuments, structures, urban textures, and social and spiritual values, which are our cultural heritage in historical continuity [1]. Therefore, the preservation of these values directly affects the quality of life and contributes to the development of a sense of belonging between generations. Although historical buildings have generally been replaced by reinforced concrete and steel structures in the last century, they still have an important share of the existing building stock. However, as building materials' durability deteriorates over time, interventions and restoration work become necessary [2, 3]. Contrary to this necessity, many of the historical buildings in the world are being destroyed and cannot be used as a result of neglect, improper planning, vandalism, and unconscious interventions. In addition, natural disasters such as fire, floods, and earthquakes trigger this process [4]. The preservation and restoration of the original architectural features of historical buildings belonging to the cultural heritage is becoming a very sensitive problem in Anatolia, as in many other regions. Many buildings that contain historical cultural values in many of the cities in Anatolia are used for different functions, such as residences, offices, and museum * Corresponding author: izzettinkutlu@artuklu.edu.tr
