‘Mega-bomb shelters’ built in Helsinki capable of accommodating an entire city

At a depth of 25 meters under the central part of Helsinki, there is approximately one of a hundred bomb shelters where, in the event of an attack, the entire population of the city can take refuge.

⠀

Tomi Rask, planning manager for the Helsinki Rescue Service, said the first security barrier is the corridor. The distance to the surface absorbs most of the explosive energy. Then there is a blast-resistant solid steel partition.

This bomb shelter in the Hakaniemi area in Helsinki was relatively recently built – in 2003. The upper floors are actively used as parking and a gym. At the same time, most Finnish shelters from the 60s and 70s were built.

It is known that in Helsinki there are many bomb shelters connected by underground tunnels that run under the entire city.
