From Candles on the Sill to Four Nights of Light: Lyon's Fête des Lumières, a Festival the City Lights

December in Lyon: the days are short, and by five in the afternoon it is already dark. In this city where the Rhône and the Saône come together, on a few nights around the eighth, small flames line the windows of its houses. Coloured candles set in glass holders — lumignons, as they are called locally — are placed by residents along window frames and balconies. On those same nights, enormous moving images are projected onto the walls of the cathedral in the old town, and the fountains of the squares and the trees along the riverbanks turn into installations of light. A single point of flame at a window and a projection that covers a whole building coexist within the same December dark. The Fête des Lumières — the festival of lights — is among the oldest festivals of light anywhere in the world, and this city kindles it every year at the entrance to winter.

What this essay sets out to read is the fact that the festival has continued as "light that the city itself lights," changing shape from a religious custom into an urban event led by the municipality. Within the category this journal calls KŌ (候) — the lineage that makes climate, season and time-limitedness the condition of a work's coming into being — the Fête des Lumières is a strikingly old case, assembled from the outset around a single day, 8 December, and around the meteorological condition of the long winter night itself.

The Windowsills of 1852

The origin of the festival goes back to the unveiling of a single statue. In 1852 it was decided that a statue of the Virgin Mary would be set on the hill of Fourvière, which looks down over Lyon. The unveiling was first scheduled for 8 September, but the Saône flooded and the statue was not ready in time, so the bishop moved the date to 8 December — the Catholic feast of the Immaculate Conception.

On the morning of the day itself, however, a storm struck Lyon. The ceremony came close to being called off; but when the sky cleared towards evening, the citizens who had been looking forward to the unveiling began, without any arrangement between them, to light fires at the windows of their own houses. Windows across the city filled with points of light, and people came out into the streets to illuminate the new statue on the hill and the chapel at Fourvière. This spontaneous "light at the window" became the prototype of the Fête des Lumières. Ever since, the custom of lining candles along windowsills around 8 December has continued in the hands of the citizens themselves, quite apart from any programme of the municipality.

What deserves attention here is that this origin was the result of being at the mercy of the weather. A flood shifted the date into December; a storm nearly wrecked the ceremony. That accident left behind a form in which the whole city lights up at once at the darkest time of the year. That the festival is a product of the season was written into the festival from the very beginning.

The Plan Lumière of 1989, the Reorganisation of 1999

It was at the end of the twentieth century that this popular custom of candles at the window was expanded into a festival on the scale of a city. The turning point came in 1989, when Lyon became the first city in Europe to adopt a "Plan Lumière" — a plan of light. This was a long-term municipal lighting policy: to stage historic buildings, bridges and riverbanks with light after dark, and to design the very landscape of the city in light. The idea of redrawing the city at night as a single work here became the language of public policy.

Against the background of that lighting policy, in 1999 the city reorganised the religious and popular celebration of 8 December into an official festival across four nights. It was named the Fête des Lumières; artists were invited, works were commissioned for squares and buildings, and the whole was shaped into a walkable event moving from street to street. The festival marked its twenty-fifth anniversary in 2024, and that count confirms that the present multi-day festival began in 1999. The operating body has been the City of Lyon throughout, and the city continues to carry the programming judgement of what is lit on which building.

The reach of Lyon's decision to take on light as urban policy does not stop at one city's festival. LUCI (Lighting Urban Community International), founded in 2002 at the city's initiative, has grown into an international network of more than seventy cities around the theme of urban lighting. Beneath a time-limited event of four winter nights lie a standing policy for designing the city's light throughout the year, and a framework for sharing it with other cities.

Making a Screen of the Architecture

At the core of the Fête des Lumières is projection mapping, which lays moving images precisely onto the walls of historic buildings. Lyon's old town retains a dense fabric of Renaissance streets and Gothic cathedrals, and during the nights of the festival that stonework is converted into an enormous screen.

Évolutions, placed at the head of this piece, is one of the high points of that practice. The artist Yann Nguema — also a member of the band EZ3kiel — did not treat the wall as a flat screen when he projected onto the front of Saint-Jean Cathedral. He took each individual stone of the cathedral as a pixel and, with software of his own making, took the architecture itself apart, reassembled it, and made it breathe in time with the music. Rather than pasting an image onto a plane, he drew the three-dimensional body of the masonry into the movement of the image — the same gesture, using up the shape of the supporting architecture without erasing it, that this journal observed in the projections onto the sails of the Sydney Opera House in a separate piece.

For the evaluation of the works there is a mechanism called the Trophée des Lumières, decided by audience vote. It is not only critics or a jury but the votes of the people who have walked the city that select the outstanding pieces. The administration programmes, artists produce, the audience votes — the design of this prize makes legible that a festival of light running on public money places its legitimacy in "the support of those who come."

The scale changes from year to year. Of the 2025 edition, the city has published that twenty-three works were placed at some twenty sites across the city and that attendance exceeded two million. For the twenty-fifth anniversary in 2024, thirty-two works were lined up. Most of the works are set in outdoor public space, and the audience does not buy a ticket: they meet the works through the act of walking the winter city itself. Once the festival ends, the cathedral wall returns to the colour of its stone, and the square returns to being an everyday square.

2015: The Choice to Put Out the Lights

How deeply this festival depends on the season and on assembly appeared most plainly in the year it once stopped. In 2015, on 13 November, just before the opening, the coordinated attacks took place in Paris and France declared a state of emergency. The City of Lyon cancelled the Fête des Lumières, an event that gathers vast crowds into the streets.

The city did not, however, leave the streets entirely dark. While calling off the official programme, it asked its citizens to light lumignons at their windows, in keeping with the custom held since that day in 1852. And onto the buildings along the riverbank, the names of the victims were projected. In place of spectacular projected works, a chain of small flames at windows and a light made of names alone filled the city. On that night, stripped of showy staging, the fact that the root of the festival lies not in the administration's programme but in the single point of fire the citizens light at their windows was made visible, paradoxically.

This episode illuminates another aspect of the category KŌ. An event that depends on the season depends not only on the season but also on a social condition: whether people can come together in it. The darkness of winter comes round every year, but whether people can go out into the streets changes with the circumstances of that year. The act of lighting a light presupposes, as much as it presupposes the weather, that people can go out into the night city in safety.

Light Kindled in the Winter Dark

What the Fête des Lumières demonstrates is a form in which a city administration can become "the body that lights the light." Unlike the curation of a museum, unlike the immersive show business of a commercial facility, unlike the time-limited release of an advertising slot, here the city itself is the programming body, binding together as a single festival, at the darkest time of the year, everything from the flames at residents' windows to the projection on the cathedral.

Tenkei in landscape painting was the concept whereby a small figure or boat brushed into a vast expanse of mountain and river gives the whole landscape meaning and scale. In December in Lyon, what serves as that "ground" is the darkness of the long winter night. The sun sets early, the air turns cold, the city goes dark — only because that enormous ma is there do the single point of flame at a window and the projection covering a building emerge as figure. Without the dark, light cannot become tenkei.

Through Vivid Sydney, which opens in the winter of the southern hemisphere, and Signal Festival, which occupies the city in the central European autumn, this journal has already looked at events of light assembled on the premise of a season. Among them, what makes the Fête des Lumières stand out is that its origin lies in the accident of one winter night, and that the fire the citizens kindled at their windows of their own accord on that night survives, more than a hundred and seventy years later, as a popular custom. Beneath the enormous projections the administration programmes, a small flame continues without going out. When the festival ends the projections vanish and the city returns to the everyday. Even so, when winter comes round again and 8 December draws near, the lights at the windows will be lit once more, one by one. The four nights of light the city lights take on meaning only with those citizens' flames as their ground.
