This unique hall, one of the most representative of the building, was built midway through the 17th century for the purpose of housing faculty meetings and other formal academic functions. It was also used as an occasional setting for theater plays.

The initial design of the Auditorium was mistakenly attributed to the mathematician Tosca, author of the well-known map of Valencia. It was the architects Felipe Rubio and Sebastián Monleón, however, who gave this hall the appearance it has today.

The hall is currently surrounded by a gallery with wooden benches upholstered in burgundy velvet. The stage is presided by a dais which includes the president’s table and ceremonial seating, also made of wood, which is accessible by seven steps carpeted in red damask with gold ornamentation. The table is flanked by two Corinthian columns which support an entablature with the counsel of Eiximenis, “ameu saviesa e bon saber, aprés Déu”, transcribed on the frieze. Above the dais is a representation of the Immaculate Conception, painted by Jerónimo Jacinto de Espinosa in 1660. At the top of the frame, two angels grasping the coat of arms of the city of Valencia remind us of the municipal origin of the Universitat. On either side of the painting are written some of the most relevant names connected to the institution.

The entire hall is topped by a large barrel vault with lunettes on the sides. An impressive bronze chandelier hangs from the center of the vault with more than fifty bulbs, flanked by four smaller chandeliers in a similar style.

The Auditorium contains one of the most important and iconic series of the Universitat de València: the gallery of illustrious individuals. To either side of the dais we find portraits of Ferdinand II of Aragon and Pope Alexander VI (born Rodrigo Borgia), the founders of the Universitat, alongside such other prestigious names as the botanist Cavanilles, the dean Vicente Blasco... for a total of 40 individuals included in the series. The most recent portrait is that of Olimpia Arozena, one of the first female professors of the Universitat and the first woman to have her portrait hung in this gallery. Circling the top of the gallery is a carved wooden balcony with a cast iron railing.

The Auditorium remains the most representative historical space at the Universitat de València. It is here where the inauguration of the academic term takes place each year, and where other formal ceremonies such as the awarding of honorary doctorates are held.
