Helsinki's Secret Underground City: Pools to Bomb Shelters
24 Sep
Summary
- Helsinki's vast underground network doubles as public leisure spaces.
- The underground city can house 900,000 Finns in case of war.
- Facilities include swimming pools, art galleries, and go-karting tracks.
Helsinki, Finland's capital, boasts a unique underground city, a testament to urban planning for both leisure and security. Initially developed from WWII bomb shelters, this subterranean network was officially master-planned by 2010 to include hundreds of man-made caves and tunnels reaching depths of up to 90 meters.
In peacetime, these spaces are transformed into vibrant public facilities. Visitors can enjoy swimming pools like the Itäkeskus uimahalli, explore art at Amos Rex, or experience a go-karting track and subway stations. These amenities are connected by nearly 200 miles of tunnels.
Crucially, this underground city serves a dual purpose. In the event of war, it can be transformed into a comprehensive bomb shelter system designed to accommodate up to 900,000 Finns. The Itäkeskus swimming hall, for example, can be prepared for defense in under 48 hours.
This innovative approach to urban living demonstrates Helsinki's responsiveness to an uncertain world, showcasing how cities can be reimagined with verve and beauty, balancing everyday needs with preparedness for emergencies.
