Çimenlik Castle and Military Museum

Çimenlik Castle (Çimenlik Kalesi) stands on the southern waterfront of Çanakkale city, directly on the narrowest navigable point of the Dardanelles strait. Sultan Mehmed II ordered its construction in 1452, a year before the Ottoman conquest of Constantinople, as part of a twin-fortress system designed to control maritime passage through the strait; its counterpart, Kilitbahir Castle, occupies the opposite European shore. The original castle was a compact, high-walled tower keep with four corner bastions, built from locally quarried limestone in under a year. Ottoman engineers subsequently enlarged and modernised the fortifications through the 16th and 17th centuries, adding lower curtain walls and gun emplacements suited to artillery. During the 1915 Gallipoli Campaign, the Dardanelles forts including Çimenlik played a central role in repelling the Allied naval assault of 18 March 1915, in which Allied battleships HMS Irresistible, HMS Ocean, and the French Bouvet were sunk or disabled by Ottoman mines and shore batteries. The castle compound today functions as both an outdoor military museum and a public park. The courtyard displays recovered naval mines, Ottoman bronze cannons, and a full-size replica of the Nusret minelayer — the vessel that secretly relaid the minefield decisive to the 1915 naval battle. Interior rooms house exhibits on the history of the Dardanelles fortifications and the 1915 naval campaign, with panels in Turkish and English. The castle's waterfront position provides unobstructed views across the strait to Kilitbahir and the Gallipoli Peninsula beyond.
