Hagia Sophia’s Dome Undergoes First Major Restoration in 600 Years
The iconic main dome of Hagia Sophia Mosque in Istanbul, one of the world’s most recognized landmarks, is being restored for the first time in over six centuries, Turkey’s Minister of Culture and Tourism Mehmet Nuri Ersoy has announced.

Speaking via social media, Ersoy stated that the dome will be reinforced to improve its resistance to earthquakes — a crucial measure considering the seismic risks in the region.
Constructed in the 6th century and known for centuries as both a church and mosque, the dome is a historic marvel of Byzantine and Ottoman architecture. Despite its age, it has never undergone a full-scale restoration — until now.
The project will combine modern technology with traditional methods and will be conducted under the strict supervision of restorers and historians to preserve the structure’s authenticity. Hagia Sophia will remain open to visitors during the works, although certain sections may be temporarily restricted.
Listed as a UNESCO World Heritage site, the restoration marks a major step toward safeguarding the architectural legacy of past civilizations.
