Hagia Sophia begins structural reinforcement of eastern semi-dome

A major restoration and structural reinforcement project has entered a new phase at the Hagia Sophia Grand Mosque in Istanbul. Following advanced modeling and static analysis, experts identified a critical need to reinforce the eastern semi-dome, which is considered a vulnerable point in potential earthquake scenarios.

Work on the eastern semi-dome will involve the installation of a steel working platform to allow access for structural strengthening and the conservation of mosaics, calligraphy, and marble surfaces. To protect the site's historical integrity, specialized printed tarpaulins will be used to maintain visual continuity, and a multi-layered floor system will be implemented to protect the original 1,500-year-old marble flooring.

Simultaneously, restoration efforts continue on the main dome, including mosaic conservation using 'facing' techniques and the installation of a temporary steel roof. The Ministry of Culture and Tourism has stated that these comprehensive works, overseen by a scientific committee, are being conducted according to a strict schedule to ensure the monument is preserved for future generations. Religious services and visitor access will continue through temporary arrangements, including the use of temporary mihrabs and minbars.
