Historical Context
During the Second World War, Helsinki, like many European capitals, was subjected to bombing raids. In a remarkable act of survival, the citizens devised an ingenious strategy: they lit decoy fires in the fields outside the city. Enemy pilots mistook these flames for the city lights, releasing their bombs over empty terrain rather than residential neighborhoods. This deception saved countless lives and preserved much of the city.
Commemorative Design
Decades later, the spirit of this wartime ingenuity was honored with a lighting installation in Vuosaari. Along both sides of Vuosaari Road, 132 light torches mounted on custom perforated steel poles stand as a reminder of the fires that once misled the bombers.
The poles are more than functional infrastructure — they are symbolic monuments. Each one supports a catenary wire network spanning across the roadway, from which the luminaires are suspended. This arrangement forms a rhythmic and immersive tunnel of light, giving drivers and pedestrians a unique spatial experience.
Lighting Phenomenon
At the base of each pole, a floodlight shines through the perforated steel. As people move through the installation, the interplay of light and surface creates a moiré effect — the base appears to flicker and burn like a living flame. By day, the row of poles and the suspended wires transform the street into a defined corridor, framing the surrounding landscape as if seen through the memory of history.
This project is both traffic infrastructure and urban storytelling. The installation connects present-day Helsinki with its wartime past, embedding memory and resilience into the city’s lighting design. It is an example of how functional road lighting can also serve as a cultural landmark.
