Sk 22 (Skyddsrum) is a civil defense bunker located in Karlskrona, Sweden. This underground shelter was constructed as part of Sweden's extensive civil defense infrastructure during the Cold War era, designed to protect citizens in the event of a nuclear attack or other catastrophic emergencies. The city of Karlskrona, situated in an archipelago, required such underground facilities since evacuation by sea was not always feasible during a crisis.
The bunker represents Sweden's commitment to civilian protection during a period of heightened global tensions. Like many similar structures throughout the country, Sk 22 would have been equipped to provide temporary shelter, basic supplies, and protection from radiation and blast effects. The Swedish government has periodically updated guidance regarding nuclear threats, reflecting ongoing concerns about global security.
Today, Sk 22 stands as a testament to Cold War military architecture and civil defense planning. While many such bunkers have been decommissioned or repurposed, they remain important historical structures that document how nations prepared for potential nuclear conflict during the 20th century.
