17/05 Helsinki, Finland (part 2) ⚠️ Booked a tour of Underground Helsinki expecting it to be remnants of the old city before they built the modern city on top. It was not‼️ It was a visit to one of the 5,500 civil defence shelters that are under Helsinki city today. The shelters are up to 5 stories underground & absolutely HUGE, many kilometres long and just as wide. They can accommodate roughly 955,000 people, enough for the city’s entire population & visitors. Dug directly into solid granite bedrock and sprayed with concrete, they’re blast-proof & radiation-shielded. ☢️ Finland‘s 1,343km eastern border is predominantly with Russia, hence the constant vigilance. During peace time, the shelters are used for recreation purposes, but in an emergency, they must be converted into a civilian shelter within 72 hours. The shelter we visited went for 4~5 city blocks, has three soccer fields and a kids play area, a coffee shop, and huge underground area that’s currently being used for parking. Every resident knows where their nearest shelter is, and on the first Monday of every month they test the warning sirens at midday. No pets allowed.😢 The day before we arrived, they detected a drone from Ukraine over the city, and the sirens were activated. What a way to live. Yikes! Apparently a lot of European countries, including Switzerland (which has the most shelters in the entire world) have these shelters as civil defence precautions. Who knew??? ☮️
