On the same day as his visit to the Vatican Library, Pope Leo XIV signed a Chirograph assigning to the Vatican Apostolic Archive and the Vatican Apostolic Library the area known as the "Fontana dell'Autoparco" and its surroundings, for the construction of a new building following modern architectural and technological standards. The document explains the decision with the significant growth, in recent decades, of the Holy See's bibliographic patrimony and the documentary output of its institutions, which has made the spaces so far available insufficient. The Pope thus preferred to build the new facility within Vatican City State itself, taking advantage of recently emerged opportunities, rather than proceeding with the extraterritorial Lateran-area solution previously identified by Pope Francis. Space in the new building will be divided equally between the two institutions, with part also reserved for other Vatican State services; the Governorate will cover the costs of state services, excluding the relocation of the car park, while the Archive and Library will set up a Vatican instrumental foundation to finance the project. In the meantime, the Library will continue to use storage space at the Pontifical Roman Major Seminary.
