### **History and Construction**

Seddülbahir Fortress was constructed as part of the Ottoman Empire’s efforts to strengthen the defense of the strait following prolonged wars with the Venetians. Built by the order of [Hatice Turhan Valide Sultan](/en/detay/turhan-sultan/llms.txt), the mother of Sultan [Mehmed IV](/en/detay/mehmed-iv/llms.txt), the fortress was designed to work in conjunction with Kumkale Fortress on the Anatolian side to protect both shores of the Dardanelles.

Although there is no definitive information about its [architect](/en/detay/architect/llms.txt), it is believed to have been designed by Mustafa [Ağa](/en/detay/aga-3/llms.txt), [an](/en/detay/an-2/llms.txt) Ottoman court architect. The foundation charter of the fortress belongs to the Hatice Turhan Valide Sultan Foundation. The fortress underwent a restoration process during the 19th century under the Ottoman rule.

### **Architectural Structure**

The fortress has an asymmetrical and tiered design, roughly in a rectangular shape. Positioned on the coastline, its outer walls feature a break in the middle. Today, the fortress has five surviving towers, with a distance of 136.5 meters between the northern and western towers. No structures within the fortress have survived to the present day.

During World War I, it served as one of the key defense points of the Gallipoli Front. On [November](/en/detay/november/llms.txt) 3, 1914, it was bombarded for the first time by the Allied forces, resulting in the first casualties on the Turkish side. It was again heavily bombarded on [February](/en/detay/february/llms.txt) 19 and February 25, 1915, by the Allied navy, leading to significant destruction.

Later in the war, the fortress was captured by the British on [April](/en/detay/april-748391/llms.txt) 26, 1915, and by the French on April 27, 1915. Due to its strategic importance, it changed hands multiple times during the Gallipoli Campaign.
