Granada Cathedral, Spain

Located in the heart of Granada, the Cathedral of the Incarnation began construction in the early 16th century at the request of Queen Isabel the Catholic, on the site where the Great Mosque once stood. Designed by architect Diego de Siloé, the cathedral is a masterpiece of Spanish Renaissance architecture, praised by writers and historians alike. While the exterior retains a Gothic structure, its main façade was designed by the architect Alonso Cano.

Previously, the cathedral was lit by high-pressure sodium vapor floodlights, which were not only energy-intensive but also in poor condition.

● Respect for cultural heritage

● Minimizing intrusive or bothersome light for observers and neighboring homes

● Energy efficiency through the use of cutting-edge light sources alongside a Bluetooth control system

● Dynamic lighting scenes that adjust to the changing environment, harmonizing with the city’s rhythms and the need for rest

● Highlighting architectural features with accent lighting and using luminaires with dynamic white technology

To implement this new lighting system, a complete 3D scan of the cathedral and surrounding buildings was conducted. This data was used to create a detailed 3D model, allowing for precise adjustments to each luminaire to minimize unwanted light spill to neighboring homes and upward into the sky. The project includes more than 20 different luminaire configurations.

The Bluetooth control system allows for the management of all 220 lighting units in the cathedral without the need for new wiring, which would have been incredibly complex to install. As night falls, the lighting system gradually dims, softening accents, or even changing the color temperature until it fades out entirely, awaiting the next sunset. Every day, as if unwrapping a gift, we can witness the gradual unveiling of every detail and accent on the main façade at Plaza de las Pasiegas, creating a unique space for contemplation and boosting its appeal as a tourist attraction.
