The International Competition for the Ornamental and Artistic Lighting of the monumental setting of the Cathedral of Santiago de Compostela and surrounding points of interest required a 360-degree architectural perspective and solid teamwork—elements that enabled us to secure third place in the final with a lighting design capable of best highlighting the unique characteristics of this UNESCO World Heritage site.

The lighting design project focuses on illuminating the Cathedral—a UNESCO World Heritage Site—and the surrounding points of historical and artistic significance.

Santiago de Compostela and its cathedral hold not only religious significance but also essential social value.
The site's historical importance necessitated a lighting solution that respects the architectural context while ensuring energy efficiency.
Following a thorough urban and anthropological analysis, the decision was made—wherever possible—to avoid installing new fixtures, thereby preventing damage to the main building and nearby landmarks. Our goal was to reuse and repurpose existing infrastructure: a site-sensitive strategy that optimizes both the electrical system and costs.


The façade is illuminated via light projection using focused beams. The entire lighting system is dimmable and features a uniform color temperature.
From a technological standpoint, to enhance the visitor experience and highlight the city's historical and cultural importance, the project incorporates an app that provides access to a detailed narrative regarding the artistic heritage of the cathedral and the surrounding areas.

At the heart of the project lies the creation of a religious, mystical atmosphere designed to welcome the vast number of tourists visiting the city each year, while also improving the daily lives of all its inhabitants, including the large student population.
