Bunker Alsou or object 221 (Protected Command Point of the Black Sea Fleet) is situated on the mountain Mishen in the Crimea, Ukraine. It is the biggest underground structure on the territory of the country except the subway.
The bunker had to become a reliable protection of the Black Sea command from a possible nuclear attack from the American side (Dropshot plan).
The bunker construction began in 1977. Mishen mountain represented a very solid monolith with no single fault. It was perfect for construction of a structure like this.
After the collapse of the USSR in 1992, the construction was almost stopped at the stage of 90% readiness. Then the object was started to be slowly plundered. They even exploded the object to get inside for gain.
The object has four levels: the main command level, residential level, hardware level and communication level, it also has two portals (eastern and western ones). The bunker goes deep into the mountain for 500 m (1640 ft) and lies at the depth of 180 m (590 ft) in the place of passage of a vertical shaft.
This is an entry to the western portal.
From the very beginning the object impresses with its dimensions. A car can easily go through it.
The deadlock that goes to the right is intended for catching a blast in case if the main entry is exploded.
The remains of the power lines are hanging under the ceiling.
It’s hard to imagine how much they spent for the construction of these miles long tunnels.
Technical inputs lead to the lower communication level.
But we go up.
Here used to be a staircase, now it’s problematic to get to the mid level.
It writes “Mines”.
It is the hardware level.
It says “No entry”.
What is hidden behind these massive partitions?
According to the map we are approaching the reactor hall.
Here it is: the reactor well. The reactor itself probably had dimensions and power similar to those mounted on submarines.
This is a part of the drainage system.
The spacious halls seem endless.
Having passed all the bunker we come to the eastern portal.
It writes” “Welcome to the as*”
From here we can see the residential complex where lived those who gurded and built the object.
And this is an abandoned crushing and screening plant, which according to some reports, served as a cover for the construction of the bunker.
Such unique structures the Crimean mountains are hiding.
