Llum BCN, the Barcelona Light Arts Festival, is back tonight (Friday, February 7), transforming the buildings and spaces in the El Poblenou district with a series of artistic installations, projections and mappings.

The annual festival, organised by Barcelona City Council, will feature light installations from 15 professional artists and creators, as well as students from the city’s colleges of art, lighting, design and architecture. The result is a circuit of light installations in which art and technology come together.
The Llum BCN 25 light arts festival itself is a great reason to extend your stay in Barcelona after visiting ISE 2025. It’s a unique opportunity to witness spellbinding performances and celebrate the city’s vibrant cultural life.
From 7-9 February, Llum BCN will transform Barcelona’s Poblenou neighbourhood into a luminous canvas of art and technology. The imaginative range of installations will include contemporary art, design and architecture, technology, and lighting design, turning the streets, squares, buildings, and parks into unmissable works of art. The 2024 edition was seen by more than 240,000 visitors.
ISE and Llum BCN are continuing their collaboration for the fourth consecutive year, bringing together the best of technology and artistic innovation. At ISE 2025 attendees have already had an exclusive preview of the mesmerising light installations of Llum BCN 25.
Maria Güell Ordis, Llum’s Art Director, added, “Our goal is to transform the urban landscape into a luminous canvas of artistic creativity and technical and audiovisual innovation that both delights and challenges the audience. Each installation is a unique expression of imagination and innovation, pushing the boundaries of what light and art, together with the help of technology, can achieve.”
Llum BCN runs from 7-9 February.
