• Fundación Iberdrola España has invested 210,000 euros in this new ornamental lighting
  • The project has improved energy efficiency by 72% and will avoid the emission of 3.2 tons of CO2 per year

Iberdrola, through its Foundation in Spain, today inaugurated the exterior ornamental lighting of the Cathedral of Sigüenza. The event was attended by the President of the Regional Government of Castilla-La Mancha, Emiliano García-Page; the CEO of Iberdrola Spain, Mario Ruiz-Tagle; the Mayor of Sigüenza, Maria Jesús Merino; the Regional Minister of Education, Culture and Sports, Rosa Ana Rodríguez; the President of the Provincial Council of Guadalajara, Jose Luis Vega Pérez and the President of the Fundación Iberdrola España Spain, Fernando García.

The Fundación Iberdrola España has enhanced the cathedral complex with this innovative project. It has carried out uniform lighting, of medium type, to avoid excess, respect the environment, and reduce light pollution.

The design has sought to obtain a “natural lighting” effect, enhancing the volumes of the architectural complex, and reducing intrusive or disturbing light. In addition, one of the most important objectives has been achieved: to offer versatility so that the new lighting can be used for different purposes: daily lighting and complete lighting for festive events, weekends, etc.

The most advanced LED technology has been used, with a very careful installation maintaining, as far as possible, the previous locations. Specifically, 150 luminaires have been installed (including projectors and linear) with a combination of warm color temperatures.

The total power installed is 6,346 W. This power corresponds to the complete lighting, while only 49 luminaires with a power of only 1.1 KW will be needed daily. The energy efficiency and savings of the project have improved by 72% and will avoid the emission of 3.2 tons of CO2 per year. All this ensures the sustainability of the installation over time.

The execution of the project has involved an expenditure of 210,000 euros. This is one more commitment of Iberdrola to Castilla – La Mancha and its permanent purpose of promoting the social value of the culture and conservation of the historical-artistic heritage of the region.

The Cathedral of Santa María de Sigüenza, Guadalajara

The cathedral complex that we see today is the result of a process of aggregations and transformations. It has a Romanesque origin, from the mid-twelfth century, and develops until the mid-eighteenth century, when it reaches its final configuration.  Subsequently, it has undergone several transformations, especially due to the damage caused during the Civil War.

Thus, while the Clock Tower with a height of 40.5 meters, was built in the fourteenth century during the bishopric of Pedro Gómez Barroso, its companion, the Tower of San Pedro, was built in the sixteenth century by Bishop Don Fadrique de Portugal, with a height of 41.7 meters. The long construction process of the Cathedral (more than eight centuries), which brings together Romanesque, Gothic, Renaissance, and Baroque elements, has made it a true legacy of the past.

Fundación Iberdrola with culture

Since its creation, Iberdrola has been committed to the energy, cultural and social development of the communities in which it operates. In this regard, Fundación Iberdrola España represents a further step in this commitment by promoting initiatives that contribute to improving people’s quality of life. One of the Foundation’s main areas of action focuses on the care, maintenance, and promotion of art and culture.

This project is in addition to others that the company has carried out in Castilla-La Mancha in recent years, including the illuminations of the Monastery of Uclés, the Old Bridge of Talavera de la Reina and the Plaza Mayor of Sigüenza, among others, as well as exhibition projects such as “El Prado en las Calles” or “Un Patrimonio de todos”.
