Sedd el Bahr Fortress
Sedd el Bahr is a 17th-century fortress at the entrance of the Dardanelles Strait on the European side of the Gallipoli Peninsula. The site features thick stone walls, rounded towers, a newly built museum in local stone, a reconstructed wooden gate, and accessible pathways that guide visitors through the different sections and ruins.
Built in 1659, the fortress was designed to guard the Dardanelles Strait as part of a defensive system with another castle across the waterway. During World War I, Allied warships bombed it repeatedly starting in 1914, and it fell to British and French forces in 1915, after which it fell into disrepair.
The name Sedd el Bahr means 'Wall of the Sea' and reflects the fortress's role as a guardian of an important waterway. Built on the order of Hatice Turhan Sultan, a powerful figure in the Ottoman court, it represented the empire's commitment to protecting its strategic passages.
The fortress is reached by walking through the small coastal village of Seddülbahir, with a ticket office and gift shop at the entrance. Metal ramps and well-maintained pathways make the site accessible throughout, and several viewpoints offer views across the strait.
Parts of the western and southern towers were intentionally left in ruins rather than rebuilt, serving as reminders of war's destruction. This conscious choice treats the damaged sections as places of remembrance, offering visitors a quiet meditation on the costs of armed conflict.
