Current conservation problems
The high-speed train line (AVE) project, Madrid-Saragossa-Barcelona-French border, resulted in the choice of planning the construction of a tunnel under the town of Barcelona. The train tunnel project goes in front of the Sagrada Familia, under the Mallorca street and in the very close vicinity of the foundations of the Cathedral’s Gloria façade. The construction of its south-east porch is not currently finished. The train tunnel also passes in front of the Casa Milà, under the Provença street. At the Sagrada Familia’s level, the diameter of the tunnel’s axis measures 12 meters and would be approximately situated 30 meters underground. The foundation piles of the cathedral are 11 to 13 meters deep.
Decision 32 COM 7B.108 took this threat into account, considering the documents and information which mainly pointed out:
The presence of cracks in various bordering buildings, where the train tunnel construction had already begun.
The World Heritage Centre and ICOMOS expressed concern regarding the possible construction of a tunnel, threatening the integrity of the Cathedral’s structure, particularly through differential displacements of the ground, greater than those planned for the Cathedral’s construction project. Furthermore, subsidences of a few centimeters had already been observed, the weight of the building causing occasional crackings in its superstructures. Therefore, it is initially a high and heavy construction, with a particular fragility. The Cathedral is currently unachieved.
