Biblioteca di Ricerca Area Umanistica (BRAU) is the university library of the Dipartimento di Studi Umanistici of the University of Naples Federico II.
The building, whose name is Sant'Antoniello a Port'Alba was founded as a convent in 1564 by sister Paola Cappellani. The monastery was expanded by annexing the neighbouring palazzo of the Principi di Conca – this closed off the original facade from public access, although the remains of the original doorway are still visible.
The present 18th-century facade was built at the same time as the building's large two-ramp staircase. After a recent restoration, the building was purchased by the University of Naples Federico II. From January 26th, 2009, it became the location for BRAU, the humanities research library of the university.
The architecture and interior decoration of the library follow the Шаблон:Ill style, especially thanks to the stucco works completed by Arcangelo Guglielmelli to restore the church in 1684. The altar is marble, with inset pearl. For a while, the main altar's painting was Bernardo Cavallino's Santa Cecilia in estasi but, after several controversies, the work was moved to the Museo di Capodimonte.
On the side altars, there are more canvas paintings like San Giuseppe by Шаблон:Ill and Ferdinando Castiglia's San Filippo Benizi. The ceiling depicts a painting of Saint Anthony, completed in the 1700s by an unknown Mannerist. There is also a wooden statue of Saint Michael Archangel from the 18th century.
