Écrin (Beacon of Light) is a monumental laser installation by 1024 architecture, commissioned for the internationally renowned Fête des Lumières in Lyon. Designed specifically for the historic Jacobins Fountain, the installation transforms the neoclassical monument into a radiant centerpiece—both architectural and symbolic.

Surrounding the fountain, 16 high-powered RGB laser beams form an immaterial structure in constant motion. This dynamic light choreography envelops the site in a luminous casing, like a jewel suspended in the urban landscape. When the beams aren't delicately tracing the contours of the fountain’s white stone, they pivot toward the sky—cutting through clouds, rooftops, and night air to create a beacon visible across the city.

The work operates on three scales simultaneously: the monument itself, the Place des Jacobins, and the broader urban skyline. This tiered interaction turns a civic space into an immersive environment, reinforcing the poetic potential of digital art as a tool for spatial storytelling. Through subtle modulation of rhythm and intensity, Écrin reimagines the public square as both a site of reverence and a spectacle of light.

The French word écrin means "jewel case"—a fitting title for an artwork that reframes a historic fountain as a treasure to be revealed through beams of precision light. Co-produced with Manifesto, and powered by ECS Laser and MadMapper, the installation is a technical and emotional landmark that celebrates the intersection of digital scenography, cultural heritage, and urban memory.
