Each February, Llum BCN transforms Poblenou into a landscape of light and experimentation. Walking its streets becomes a way of exploring digital installations that interact with the surrounding architecture and public space. A different Barcelona emerges, where art, design and technology meet in temporary and often unexpected ways. No specialist knowledge is needed, just curiosity and a willingness to look again at familiar streets. It brings together those interested in how artistic practice can reshape the city in everyday ways.
