In order to defend the city both from land and from the sea, the city was surrounded by a ring of defensive structures. Of greatest interest to travelers is the 30th Coastal Artillery Battery. In 1949–1954, the battery was restored (instead of the old two-gun turrets, the MB-3-12-FM three-gun turret mounts were installed, taken from the battleship Frunze (formerly Poltava) of the Baltic Fleet, power equipment was replaced, a new, most advanced for that time, the "Bereg" fire control system with a radar station and heat direction finders) and reorganized into the 459th separate tower artillery division. Until the mid-1990s, as part of the 778th artillery, and then the 51st missile and 632nd missile and artillery regiments, the division provided coastal defense of the Main Base of the Black Sea Fleet. In 1997, the personnel of the division was transferred to the Caucasian coast, and the fortifications were transferred to the 267th conservation platoon.
