Çimenlik Castle consists of an outer castle and an inner castle. Its outer wall measures 150x100 meters and its height is 11 meters. There were 9 bastions on the walls. The city wall on the sea level was demolished in time of Selim III and platforms were built according to the changing weapon technology. In its garden, there is a gunpowder building and two mosques built during the reign of Fatih and Abdulaziz. On March 18, 1915, the artillery that was thrown from the British ship Queen Elizabeth and left unexploded in a 2-meter hole in the northern wall is still in place. In the garden of the museum, cannons of various sizes, artillery trucks, antitanks, mines and the remains of a German submarine extracted from the sea are displayed. Apart from these exhibition venues, the temporary exhibition hall called Muavenet-i Milliye Hall, to the left of the museum entrance door, frequently hosts a new exhibition. There is a very rich souvenir shop next to this hall. (ÖZDEM, Filiz (Ed.), Love, Wars, Heroes and Çanakkale; Veysel Tolun, The Gate of the Ottoman Empire to the Mediterranean.
