This catenary lighting system, designed for downtown Milan, effectively combines technology and aesthetics to match the unique characteristics of the city. Our proposal received approval from the Sopraintendenza Archeologia, Belle Arti e Paesaggio per la città metropolitana di Milano. The project required careful coordination to meet the photometric needs of the streets while ensuring that the lighting fixtures harmonized with the surrounding architecture. As a result, we adjusted the spacing between the lighting devices to avoid obstructing views of critical architectural elements such as windows, pediments, columns, and other decorative features.
