Biblioteca Piccolomini

About

The Biblioteca Piccolomini, located in the heart of Siena’s Duomo complex, is a treasure trove for art lovers and history buffs alike. Housed in a Renaissance pavilion, the library showcases an extraordinary cycle of frescoes by the talented Pinturicchio, celebrating the life of Pope Pio II and the patron saint of the city. Visitors are treated to an intimate gallery that showcases the early years of the papacy, the coronation, and the cardinal’s diplomatic missions, all illuminated with vibrant allegories and intricate iconography. Beyond the frescoes, the collection includes the famed marble tri‑statue of the Three Graces, a copy of a Roman original, that graces the main hall. The space is curated with careful attention to lighting and conservation, making it a perfect destination for research students, school groups, and anyone curious about the intersection of art and history. Tours are available through the Duomo’s ticketing office, with a single admission ticket granting entry to the library, the cathedral, and other museum sites in the complex. Families can enjoy free admission for children under six, while adults and older children pay a modest entry fee. The library’s tranquil environment and richly detailed artworks provide a memorable day for all kinds of visitors.
