About Biblioteca Vallicelliana
Saint Filippo Neri, the influential Counter-Reformation priest who founded the Congregation of the Oratory, established this library in 1565 from his own personal collection, and left it to his congregation on his death in 1595 — a foundational bequest that grew, over subsequent centuries, into one of Rome's most significant historic collections of theology, church history and patristic scholarship, now numbering roughly 140,000 items.
The library is physically housed within the Oratorio dei Filippini, the Oratory Fathers' headquarters complex adjoining the church of Santa Maria in Vallicella (better known simply as Chiesa Nuova, 'the new church'), a building substantially designed by Francesco Borromini in the 1630s and 1640s — meaning the library's own architectural setting is the work of one of the two greatest architects of Roman Baroque, a fact that many visitors to the church next door never realise extends to the library within the same complex.

The collection's genuine treasures include roughly 3,000 manuscripts in Latin and Greek, among them a Bible believed to have belonged to Alcuin of York, the influential Carolingian scholar, dating to the 9th century, and a 12th-century lectionary — material of real significance to medieval and Church history scholars, even if the building's Baroque grandeur is what draws most casual visitors who happen to find it.
Inaugurated formally by Borromini himself in 1644, the main reading hall — sometimes called the Borromini Hall — is a rectangular, coolly majestic space that gets only a fraction of the foot traffic of the church next door, making it one of Rome's genuinely under-visited architectural interiors for anyone willing to seek it out specifically.
