Sol A Solo is a fictional cultural festival set in Lisbon’s Estufa Fria, created to spark dialogue about our relationship with the planet and to celebrate diversity in all its forms. Through a multidisciplinary program, it encourages reflection and action on environmental and social issues, uniting artists, scientists, farmers, chefs, winemakers, philosophers, activists, and other local voices. The goal of this project was to design the festival’s visual identity and a range of communication materials, reflecting the event’s natural and sustainable ethos.
