The City Inside the Mountain: Finland Took 2,000 People Underground While Europe Watched

The DW correspondent opens with a blunt question: if disaster struck tomorrow, would your city cope? To answer it, the crew descends into Luola in Kuopio, in central Finland. During the Shelter 2026 exercise on 2-3 September 2026, more than 2,000 residents join rescue crews, volunteers and the municipality for hours behind sealed doors.

Luola is a dual-use site beneath the Savilahti sports and events centre. On ordinary days it works as a sports hall; in an emergency it is designed to shelter up to 7,000 people. Completed two years ago, it is presented as one of Europe's most modern civil shelters, and this drill is its first near-full test in that second role.

The scenario goes beyond explosions. Cyberattacks have knocked out power and water in Kuopio and the missile threat has risen. Soldiers in protective suits measure radiation at the entrance while pressure-rated doors close inside. Officials say only such a rehearsal can answer practical questions about water, heat and crowd psychology.

Life inside looks surprisingly ordinary. Some play cards, some knit wool socks, some check their phones. The main hall is split by screens into bays of about 200 people each. Beds are too few for everyone, so rest runs in shifts, and just over 2,000 participants share 60 dry toilets. One participant says plainly that the hall is warm and loud, and that staying for days would wear people down.

The numbers behind the network are striking: roughly 50,000 civil shelters with room for about 4.8 million people. A building duty in force for decades requires shelters in larger properties. Inside the network sit around 100 large rock-hewn sites hardened against nuclear, biological and chemical effects; small basement shelters in apartment blocks offer simpler cover.

The cultural layer runs deeper than concrete. Finland shares a 1,340-kilometre border with Russia, joined NATO in 2023, and keeps the memory of the 1939-1940 Winter War alive. Speakers describe grandfathers who fought for independence and a watch that now falls on them. The shared tone is not fear: we are not scared, we want to be ready.

A retired colonel serving as Kuopio's security specialist gives the model its name: comprehensive security. State agencies, firms, municipalities and volunteer groups act as one structure. He names unbroken general conscription as the key lesson: compulsory for men and voluntary for women, so security becomes something citizens help produce rather than only consume.

The secret sits in peacetime use. The shelters do not wait empty; children play there, families train there, the site works like a neighbourhood facility. That keeps the building maintained and the routines familiar. A volunteer at the drinking-water point sums it up: I am here to help my community, and the normal endurance span is 72 hours.

The camera's glance beyond Finland is more anxious. The eastern flank feels the threat up close while distant capitals move slowly. Germany plans a 10-billion-euro civil protection package with a shelter map, specialist vehicles and field beds, but much of it is still at the announcement stage. Inspections in Cyprus finding about 200 of 2,500 listed shelters unusable show the state of Europe's Cold War inventory. The EU cannot order shelter construction under Article 196, and its rescEU stock is mostly tents and prefab camps.

On the second morning the doors open, participants return to classrooms and jobs, and the hall turns back into a sports venue. The message that remains is simple: here readiness is not a panic that starts when danger knocks but a habit that never stops. Trust, neighbourliness and drill discipline look like the cement of the model.
