In Grasse, BOA enhances the transformation of the historic center through a sensitive heritage scenography and an urban lighting strategy that reveals the city’s singular character. Night extends the day’s final gradient across the city’s relief; the towers and cathedral emerge through precise, measured light. Historic lanterns create a warm and cohesive framework, while at the heart of the squares a constellation rises from the ground. Discreet accents integrated into furniture and façades highlight alcoves, stairways, and pathways. Levels gradually modulate, allowing the city to recover its natural darkness. An evolving nocturnal composition serving heritage and contemporary uses.
