Hagia Sophia Undergoes Major Seismic Retrofit: Largest Intervention in 150 Years to Protect Historic Landmark

Istanbul, Turkey – A comprehensive restoration project is underway at the Hagia Sophia in Istanbul, focusing on seismic reinforcement to protect the iconic structure from future earthquakes. This marks the most significant intervention in the building's 1500-year history in over 150 years. The restoration includes replacing worn lead coverings, upgrading the steel framework, and reinforcing the Hagia Sophia's minarets, main dome, and vaults. A protective framework system will be installed around the structure to allow for safer work and academic study of the building's layers, including damage from past fires and earthquakes. While the restoration is in progress, religious services will continue uninterrupted. Modern, lightweight materials will be used to preserve the cultural heritage site, and the building will remain open to the public throughout the process. The public will be able to transparently monitor the interventions on the building.
