He intended to open the seminary in the Oratory of Santa Maria a Ponterosso, in the Florentine comune of Figline e Incisa Valdarno.

[1] The seminary at Fiesole was founded in 1637 by Bishop Lorenzo della Robbia, with the intention of training priests in the newly formed precepts of the Council of Trent.

[2] Della Robbia, who was educated at the Jesuit Roman College, designed the seminary's curriculum to include writing and grammar (as many of the arriving students would be illiterate), humanities (which meant history and poetry), rhetoric, philosophy, cases of conscience, and singing.

[2] In 1782, an altarpiece which dates to 1520 and was created by Giovanni della Robbia was moved from the Church of Saint Peter in the Petrognano frazione of Barberino Val d'Elsa and installed in the eighteenth century chapel.

It depicts the Virgin Mary crowned by angels and amidst Saints Peter, Donatus, John the Baptist, and Romulus.

[4][5] In addition, there is a work by Luciano Guarnieri titled Il Vangelo di Venturino, which consists of 45 panels depicting the life of Jesus Christ.

Scientific equipment for studying physics, chemistry, and natural history were added in the nineteenth century.
