City Planners Chamber warned, Eurasian Tunnel, will affect the historical texture adversely

The City Planners Chamber had warned, the Eurasia Tunnel would negatively affect the historical texture: Slippage and liquefaction were detected on the floor of the Topkapı Palace. It is stated that mega projects such as the Eurasia Tunnel triggered the sliding in the floor of Topkapı Palace. In the report prepared by the Chamber of City Planners about the Eurasia Tunnel in 2011, “Although the Land Walls in the west of the Historic Peninsula were declared as World Heritage Assets through similar processes, the cultural assets of the part of the Eurasia Tunnel route passing through the southern end of these walls it is almost impossible to affect it ”.

The damage caused by the 'mega projects' implemented in Istanbul by ignoring the warnings of the experts is revealed day by day.


During the restoration project in Topkapı Palace, one of the most important works of the Historic Peninsula, serious cracks were found during the dismantling of cement plasters on the walls of the basement of Fatih Mansion, where the treasury section was exhibited last year.

In the same period, a pit with a diameter of 3 meters and a depth of 1 meter was formed in front of the Justice Tower in Topkapı Palace.

At the beginning of April in 2015, the wall of the tea garden had collapsed in the sea-facing part of Gülhane Park. At that time, the museum officials said in a statement on the same axle Konyalı Restaurant's wall collapsed, stating that the palace on the side of the sea facing the risk review was announced.


It was determined that the reason for the giant clefts formed on the walls and domes that brought Topkapı Palace to the point of collapse was a slip and ground liquefaction towards Sarayburnu on the floor of the historical building.

It is believed that the slippage took place over many years and the fact that Topkapı Palace drainage system was old and the system did not work in places increased the liquefaction on the ground.


One of the most important reasons for the shift was expressed by experts, who had large scale projects such as Marmaray and Eurasia Tunnel.

Warnings were included in the Eurasia Tunnel Project Evaluation Report prepared by the TMMOB Chamber of City Planners Istanbul Branch regarding the damage to the historical texture of the Eurasia Tunnel, which is stuck like a dagger in the heart of the Historic Peninsula, the most important historical area of ​​Istanbul.

In the report prepared in 2011, it was emphasized that it was impossible for the Eurasia Tunnel project not to affect the historical texture, and this evaluation was included:

“The Historic Peninsula is able to hold the cultural, natural, historical and archaeological values ​​of Istanbul together; Since it is one of the most important identity items of urban, national and international importance, all land use and transportation decisions in this area should be taken as a result of highly sensitive measurements and evaluations. Sustainability of the area should only be ensured through abstract and tangible heritage values ​​within the framework of conservation principles. From this perspective, the Eurasia Tunnel Project, at first glance, perceives that it does not have a negative impact on the Historic Peninsula because it uses the coastal road route and passes over the embankment area, but it will not be the case when the subject is examined in detail, how the project may affect the Historic Peninsula with direct and indirect effects. will be easily understood.

The Eurasia Tunnel Project route and the areas it affects, from the point where it touches the Historic Peninsula, are the region where Istanbul's undeniably superior values ​​are located in terms of its historical and cultural heritage. In addition to the monumental works such as Topkapı Palace, Hagia Sophia and Blue Mosque, which are included in the 'Sultanahmet Archeological Park', which was included in the UNESCO World Heritage List as a World Heritage Asset in 1985, the outstanding universal value of this region constitutes the superior universal value of this region.

Maintaining the integrity of these values ​​without deterioration and not losing their originality are important for contemporary protection and UNESCO pays attention to the application of these principles in all countries of the world. The Marmara Sea walls along the route and the archaeological heritage dating back to the Neolithic period in Yenikapı are the most important areas that this route will affect and transform. Although the Land Walls located to the west of the Historic Peninsula have been declared as World Heritage Assets through similar processes, it is almost impossible that the part of the Eurasia Tunnel route passing through the southern end of these walls does not affect the cultural assets in this region. ”
