As part of the Llum BCN 2026 festival, Barcelona once again transformed into a vast urban stage where light activated architecture, bodies, and public space, reaffirming the role of culture as a tool for urban transformation. In its 15th edition, the festival closed with a record 300,000 visitors, consolidating an upward trend in audience numbers and confirming its cultural and civic impact.
Coinciding with Barcelona's designation as World Capital of Architecture 2026, Llum BCN was much more than an artistic event: it became a contemporary reading of the city through light, sound and visual experimentation.
AÜC: Body, Light and Memory in Public Space
Among the unpublished works presented this year, AÜC stood out, an installation by visual artist and performer Laia Estruch, developed in collaboration with BENITO URBAN and presented in Oliva Artés.
AÜC is a work situated between performance, sculpture, and light installation. Using an advanced capture system with 48 cameras recording simultaneously, the piece generates an almost holographic presence: a suspended body that is drawn in four-dimensional space, activated by gestures, twists, and an intense sound dimension. The work is constructed from:
- Light as a spatial structure
- The voice as an extension of the body
- Movement as a generator of memory
In AÜC , technology is not an end in itself, but a means to amplify the presence of the body and its relationship with space, situating the work in a hybrid territory between the physical and the intangible. Far from a figurative representation, the installation investigates how to preserve the trace of an ephemeral bodily action and how the body can activate urban space through listening and presence.
An investigation aligned with BENITO URBAN 's commitment to contemporary creation and the cultural activation of public space.
What is Llum BCN?
Promoted by the Barcelona City Council and developed under the artistic direction of Maria Güell, whose curatorial vision has been key to consolidating the festival's contemporary identity, Llum BCN is an annual light arts festival that invites artists, designers, architects and schools to intervene in urban space from an experimental and open perspective.
Under the motto 'Nocturnal Landscapes', the 2026 edition proposed a sensitive reading of the city, combining art, technology, architecture and citizen participation. The festival maintained its free and accessible nature, reinforcing its democratic vocation and its direct connection with the citizens. The program included:
- 12 professional facilities
- 18 academic facilities of design schools
Sant Martí and the city as a sensory setting
The Sant Martí district was once again the epicenter of the festival. Between the Glòries tower, the Disseny Hub, and the new architecture of Poblenou, the city was transformed for three nights into a nocturnal landscape with a strong cinematic character.
Light ceased to be merely ornamental and became a tool for urban interpretation, revealing new layers of meaning in facades, plazas, and buildings. The installations engaged in a dialogue with the existing architecture, generating immersive experiences that invited visitors to explore the city from a different perspective.
300,000 visitors and a consolidated impact
With 300,000 visitors, Llum BCN 2026 matched the figures of the previous edition and consolidated its success after years of continuous growth. The festival not only attracted local audiences but also reinforced Barcelona's international profile as a creative and cultural capital.
In the context of the World Capital of Architecture, the festival expanded its presence to all districts of the city, placing installations in landmark buildings and spaces and demonstrating the potential of light as a tool for urban activation.
Light as a tool for making a city
Llum BCN raises a key question: how do we want to inhabit our cities? Through temporary interventions, light redefines uses, perceptions, and relationships in public space, transforming the everyday into an experience.
At BENITO URBAN , participating in projects like AÜC reinforces our commitment to:
- Collaboration with contemporary artists and creators
- Culture as a driving force for the city
- The sensitive activation of public space
- The design of more human and experiential urban environments
Llum BCN 2026 bids farewell, leaving behind a city that, for a few nights, forgot its functionality to become a living landscape. A reminder of that light also builds cities.
