The intervention in this Cathedral, which has been a National Monument since 1910, has always sought to enhance the existing heritage by restoring the building and creating appropriate infrastructure. During the refurbishment, key concepts such as reversibility, sustainability, versatility and simplicity were respected, while respecting the heritage.
The main aim of this rehabilitation project was to restore the material, historical, artistic and cultural integrity of the cathedral complex, focusing particularly on its movable and integrated heritage (altarpieces, paintings, imagery, furniture, tiles, mural paintings, jewellery and metals), which had previously been identified, catalogued and inventoried.
