Eyüp Sultan Mosque Restoration: A Century-Spanning Transformation from a 2026 Perspective

Eyüp Sultan Mosque, the spiritual heart of Istanbul and one of the significant places of worship in the Islamic world, has been the scene of numerous repairs and renovations throughout history. Today, Eyüp Sultan Mosque restoration works are being carried out with great meticulousness to ensure this sacred space is passed on properly to future generations. As we reach 2026, we can evaluate the mosque's transformation from past to present and its conservation efforts with a clearer perspective.

The History and First Repairs of Eyüp Sultan Mosque

Eyüp Sultan Mosque was built by Sultan Mehmed the Conqueror after the conquest of Istanbul, over the tomb of Abu Ayyub al-Ansari. Construction of the mosque began in 1458 and was completed in a short time. As one of the first major structures of the Ottoman Empire, the mosque has been exposed to many natural disasters and wear and tear over time.

The first comprehensive Eyüp Sultan Mosque restoration efforts were carried out shortly after the mosque's foundation, in the 18th century during the reign of Selim III. During this period, the mosque was largely rebuilt and began to bear the traces of Ottoman Baroque architecture. These restorations largely shaped the current outlines of the mosque.

The Importance of Selim III Period Restorations

The restorations carried out during Selim III's reign were a critical turning point for the architectural identity of the Eyüp Sultan Mosque. A more ornate and detailed architectural understanding was adopted, differing from the original structure. These works not only involved physical repairs but also enhanced the aesthetic and artistic value of the mosque.

• Strengthening of the mosque's main dome.
• Reconstruction or repair of the minarets.
• Use of gold leaf and pen work in interior decorations.
• Addition of the Hünkar Kasrı (Sultan's Pavilion).

Recent Eyüp Sultan Mosque Restoration Processes

Eyüp Sultan Mosque has also undergone various repair and strengthening works in the 20th century and early 21st century. Especially due to its location in an earthquake zone, applications for the structural soundness of the mosque have been of great importance. These restorations have generally been carried out by the General Directorate of Foundations and performed by expert restoration teams.

In the last 30 years, significant steps have been taken in areas such as weathering on the stone facades of the mosque, renewal of dome leadings, and improvement of interior acoustics. These works aimed both to preserve the historical texture of the mosque and to provide a better experience for worshippers. The ongoing Eyüp Sultan Mosque restoration projects ensure its longevity.

Works in the Early 2000s

Restorations carried out in the early 2000s mark a period when the mosque met modern conservation techniques. During this period, particular emphasis was placed on strengthening the mosque's foundations and cleaning and consolidating the stones used on the exterior facade.

• Foundation and wall strengthening injections.
• Cleaning of facade stones with laser and steam techniques.
• Conservation and restoration of wooden elements.
• Protection of calligraphy and illumination artworks within the mosque.

Eyüp Sultan Mosque Restoration and Future Vision from a 2026 Perspective

As we reach 2026, many new technological possibilities and conservation approaches are being adopted in the Eyüp Sultan Mosque restoration process. In current restorations, not only physical repair but also sustainable conservation approaches that highlight the cultural and spiritual value of the mosque are effective. In this context, issues such as protecting the mosque from environmental impacts and better managing visitor flow are also on the agenda. The future vision also touches upon the mosque's ongoing artistic dialogue, as explored in Eyüp Sultan Mosque in 2026: Stories Rising from its Minaret and Contemporary Art Movements.

In the vision for the future, the integration of the mosque into digitalization processes is also important. With methods such as 3D modeling, virtual tours, and digital archiving, the historical and architectural features of the mosque are being carried into the future. In this way, it becomes possible for those who cannot physically visit the mosque to experience this sacred place.

Sustainable Conservation and Digitalization

The sustainable conservation approach aims to increase the cost-effectiveness of restorations while also ensuring the mosque's harmony with its natural environment. Digitalization is a powerful tool both for documenting conservation processes and for promoting the mosque to wider audiences. The use of advanced technologies in preservation efforts reflects a global trend in heritage conservation, as detailed by organizations like ICOMOS (International Council on Monuments and Sites).

• Use of environmentally friendly materials in restoration works.
• Energy efficiency in the mosque's air conditioning and lighting systems.
• Monitoring the instantaneous condition of the mosque with structural monitoring sensors.
• Presenting historical information to visitors with augmented reality (AR) applications.

Architectural Features of Eyüp Sultan Mosque and the Contribution of Restorations

Eyüp Sultan Mosque is a unique structure bearing traces from different periods of Ottoman architecture. It encompasses a wide spectrum, from early Ottoman architecture during its initial construction to the Baroque influences of the 18th century.
