Meeting for Joint Research on Conservation and Restoration of St. Michael’s Church (Keşlik Monastery) (Part 2)



The Japan Center for International Cooperation in Cultural Heritage is conducting a joint research project on the conservation and restoration of mural paintings on the interior walls of St. Michael’s Church (Keşlik Monastery) in Cappadocia, Turkey, in cooperation with domestic and international experts and academic institutions.
From June 21 to July 15, 2025, an on-site investigation was conducted in accordance with a conservation and restoration plan formulated based on the findings of the previous year’s field study. The work focused on cleaning the apse area of the church and reinforcing deteriorated plaster layers in the nave that were at risk of detachment. The wall paintings in this church had been obscured by a thick layer of soot for over a century, and no one in recent times had seen their full imagery. Through the careful and safe removal of these long-accumulated deposits during the recent cleaning process, the original colors and fine details of the paintings have been vividly revealed. This has enabled a more detailed examination of the initial iconographic design and painting techniques, yielding new insights into the chronology and stylistic characteristics of the works. Of particular significance is the fact that the practicality of the technical approach taken to the conservation and restoration, systematically developed through this research, was validated during the actual intervention. This constitutes a highly meaningful outcome, both academically and in terms of conservation practice.
This joint research project is an international conservation and restoration initiative led by the Tokyo National Research Institute for Cultural Properties, in collaboration with specialized institutions and universities both within and outside of Turkey. In the current phase of the project, scientific conservation methods and three-dimensional measurement technologies were introduced with the aim of assessing the condition of the wall paintings during the conservation and restoration process. By examining the subject from multiple scientific and physical perspectives, the project seeks to establish conservation and restoration methods that are closely aligned with the specific characteristics of the wall paintings. This multifaceted and meticulous approach has been highly regarded as a pioneering case without precedent even within Turkey and has drawn significant attention. Moving forward, we aim to continue these meaningful activities in response to such expectations, contributing to the conservation and sustainable use of cultural heritage.
