The renovation of the roofs of the Santiago de Compostela Cathedral has been recognized with the prestigious Premio Próximo 2026, an award granted to architects Iago Seara Morales and Juan Orozco Corredoira that highlights technical rigor, scientific research, and executive excellence in historical heritage.
The project, led by both authors alongside the Fundación Catedral de Santiago and the construction company PECSA, relied on the key participation of KIMAK to bring to life the construction solutions that resolved the historical humidity issues affecting the temple's transept crossing.
When granting the award, the jury highlighted:
“A thorough study and preliminary analysis, the precision of the technical solutions required in the conservation works of the asset, and the natural consideration of the monumental character of the intervention.”
To meet this demanding architectural challenge, KIMAK custom-designed, manufactured, and installed an innovative aluminum structure spanning 12 kilometers in length, which successfully reduced the weight of the roof by 750 tons. Supported by cutting-edge technology such as point cloud scanning, we installed more than 4,800 new stone slabs in a staggered pattern.
The result is a unique rear-ventilated roofing system that, in addition to waterproofing the monument, renders the slabs reversible and accessible to facilitate future maintenance.
A milestone that has required more than 3,500 hours of exclusive dedication from our team in one of the most complex and awe-inspiring heritage works of recent decades.
