A comprehensive restoration project has commenced at Istanbul’s iconic Hagia Sophia, aiming to fortify the 1,500-year-old UNESCO World Heritage site against potential earthquake damage. Architect Hasan Fırat Diker is spearheading the initiative, which is considered one of the most significant preservation efforts in modern Turkey.
Originally constructed in AD 537 during the Byzantine Empire, Hagia Sophia has endured numerous seismic events over the centuries, including the collapse of its original dome in 558. The current restoration focuses on reinforcing the central dome, examining key structural pillars, addressing vulnerabilities in the semi-domes, and removing the dome’s lead covering to assess hidden damage.
The urgency of the project has been heightened by recent seismic activity, notably a 6.2-magnitude earthquake near Istanbul last month. Given Turkey’s location atop two major fault lines, the risk of earthquakes remains a significant concern. Diker emphasized the importance of the restoration, stating, “We are not just responsible for this building but to the entire world public.”
Hagia Sophia’s rich history includes its transformation from a cathedral to a mosque following the Ottoman conquest in 1453, its conversion into a museum in 1935, and its reclassification as a mosque five years ago—a decision that sparked international debate. Despite these changes, the structure continues to attract millions of visitors annually.
The restoration team aims to maintain public access during the works, with scaffolding designed to allow visitors to experience the site. Additionally, the project may uncover historical murals from the Ottoman era hidden beneath layers of gold and yellow surfaces. While no specific timeline has been set, the restoration is expected to be a landmark endeavor in preserving both the spiritual and cultural legacy of one of the world’s most significant architectural landmarks.
As Istanbul continues to grapple with the threat of future earthquakes, the restoration of Hagia Sophia stands as a testament to the city’s commitment to preserving its historical heritage for generations to come.
