Johannes shelter in Stockholm is the third largest public nuclear shelter in the capital. Constructed in the 1950s, it had the capacity for around 5,000 people. It is formed of two tunnels on top of each other, and is now used as a car park. There were four entrances in total.
Pedestrian entrances had coloured handrails on the stairways which helped the flow of large numbers of people enter smoothly. Like many other shelters the shelter is located close to or directly underneath a church, this being the Johannes church.
