Katarina rock shelter

The three-level underground facility spans across multiple floors beneath the streets of Södermalm, incorporating reinforced concrete walls and specialized ventilation systems.

Built between 1952 and 1957, this nuclear shelter emerged as a response to escalating tensions during the Cold War period in Stockholm.

The shelter represents Swedish civil defense strategies of the 1950s, reflecting the national approach to protecting citizens from potential nuclear threats.

During regular periods, the structure functions as a parking facility while maintaining its capacity to shelter 20,000 people in emergency situations.

The facility contains specialized storage basins designed to hold 200,000 kilograms of ice for cooling purposes during potential nuclear events.
