The construction of the Namazgah Bastion, which is composed of 26 bonnets and is situated on the sea side of the road that can be accessed after crossing the Kilitbahir Castle, was initiated at the suggestion of Baron De Tott who was commissioned for the modernization of the Ottoman Army. It is the first and largest bastion built on the narrowest location of the Dardanelles Strait. The bastion acquired the qualification of Central Bastion together with the outbuildings. 

This bastion was the headquarters of the 4th Heavy Artillery Regiment to which the batteries of the regional bastions were attached during the Battle of the Dardanelles. Hence, it was a permanent target of the fleet of the Allied powers. The bastion had 16 coastal artillery cannons. Two of these were long-range while 14 were short-range. Only 2 of these cannons were actively used in the naval battle while the others were not used due to their insufficient range. 

The location on the main axis of the bastion is known to have been used as the Operation Center of War during the Dardanelles Campaign. Artifacts from the Battle of the Dardanelles are exhibited at the bastion, which was recently restored in 2005-2006 by the Ministry of Culture and Tourism and opened to visitors on March 18, 2006. The bastion’s 12 exhibition display boards show historical information regarding the battles. After this section is a short 7 minute film of the naval battles on the inner side of the bonnets. A sound presentation broadcasting wartime communications may be found in one of the bonnets. In this section, photographs of the Allies’ sunken battleships are also displayed.
