Özmen, Can

The aim of this thesis is to define Hagia Sophia’s current condition and problems derived from re-functioning as a mosque, discuss its historical background and intervention history to assess existing and potential values for future interventions from a viewpoint of an art and architectural history and conservation of cultural heritage. For this aim, the historical background and intervention history, analysis of the current condition and effects of the latest interventions, and finally a comparative study and value assessment were made to determine the distinctive features and values of the heritage in this study. It is understood that the building witnessed several of change in functions and interventions which can be evaluated under four periods, and it is important to note that the building was seldomly used as a mosque and abandoned before the 19th century according to the notes of travelers. To conclude, today while the Hagia Sophia is in good condition structurally and displays distinctive historical, symbolic, artistic and architectural values, latest implementations resulted in the degradation of the values and they are inadequate for presenting and conserve the values of the of the heritage as frescoes which are not suitable for Muslim at the dome, naos, and bema of Hagia Sophia were covered with curtains and opus alexandrinum tiled floor at the naos under the dome bay was obscured under carpeting, and other interventions were distorting the perception of the space.
