Series of restorations and reforms appointed by the Bishop of Mallorca, Pere Campins, for the Cathedral of Palma de Mallorca.
Although the works were allocated to Gaudí in 1902 and that Gaudí travelled immediately to the island, the works did not start until the year after. They consisted of the transfer of the Gothic and Baroque altarpieces, the shift of the choir, the opening of the Trinity Chapel, the installation of new pulpits, the opening of Gothic windows, the fitting of stained-glass windows, the installation of a canopy, the decoration of the walls and the making of furniture.
Gaudí surrounded himself with collaborators depending on the needs of the project, such as the architects Guillem Reynés, Joan Rubió and Josep Maria Jujol, and the painters Iu Pascual and Jaume Llongueras. The intervention on the exterior was carried out following the ogival style between 1910 and 1912, whilst that inside and the glass windows were carried out between 1904 and 1914. In that last year, because of disagreements with the building contractor, the works were interrupted and were not continued because the bishop, who had been the main promoter, died the year after.
