Balaklava, Ukraine
Balaklava is a picturesque town in Ukraine that hides a series of tunnels in the mountain. It was a part of the Soviet project to build a submarine base with a water channel and dry dock. It was called Object 825 GTS and created in the ‘50s to prevent enemies from spotting the submarines. The network had a nuclear shelter to protect the residents of the nearby town should a nuclear attack happen. It also had a weapon storage facility. In 1996, the base was abandoned and turned into a Cold War Naval Museum.

Object 280
The Balaklava Soviet Naval Museum also had a huge technical and repair base code known as Object 280. It was created to store and maintain nuclear weapons transported to the Tavros mountain tunnels. Object 280 was a special tunnel used for loading equipment during wartime. It made sense because Object 825 GTS was created to maintain, repair, and store vessels from Project 633 and 613.
