The construction of the Archiginnasio dates back to the 16th century, when Piazza Maggiore was drastically remodeled under papal orders; the Fountain of Neptune was built during this same period. The construction of the Archiginnasio was commissioned by Pope Pius IV through the papal legateCharles Borromeo and the vice-legate Pier Donato Cesi during the years of the Council of Trent, who then entrusted the project to Antonio Morandi. The building was begun at the end of February 1562, built very quickly, it was inaugurated on October 21, 1563. The goal of this project was to create a single place where the Schools of the "Legisti" and "Artisti", previously located in various places across the town, could be hosted together. The building of the new "Schools" was named Archiginnasio after the classical term which was used to designate the Studium, as the University was first called, of Bologna. The Archiginnasio ceased to be a University in 1803 when the University was moved to Palazzo Poggi where it is still located today. Scuole Pie were housed in this building for a few years and later, from 1838 onwards, were replaced by the city library. Archiginnasio Municipal Library is the largest library in Emilia-Romagna. It was first established to keep the books collected from the closure of the religious orders made by Napoleon. At present it boasts 850,000 volumes and pamphlets, including 2,000 incunabula, about 15,000 16th century editions, 8,500 manuscripts, letters, collections of autographs, prints and drawings, and 250 archives. All of this material, handwritten and printed collections, are of the utmost importance. They deal with the civil, cultural, religious and social history of Bologna and its territory. Upon entering, visitors are asked to hand over all bags and writing materials which can be picked up when leaving.
The building
Externally the building presents a porch some 139 meters long comprising thirty arches supported by sandstone columns, inside a central courtyard with two line of loggias that surrounds the former church of Santa Maria dei Bulgari. Two stairways lead to the upper floor where are located the study rooms of the legisti, and the artisti. Each of the legisti and the artisti had five classrooms in their respective wings, however only the legisti, who were considered the university's top students, had their classrooms in the main hallway. At the end of each wing there are two great halls, one of them has now become the library's reading room, the other one is now used as a congress room and is known as "Sala dello Stabat Mater" in memory of the first performance of Rossini's Stabat Mater, directed by Gaetano Donizetti, on March 18, 1842. The walls of the building form an enormous heraldic complex, made up of six thousandcoats of arms painted on its walls. The honor of putting a coat of arms on the walls was reserved for those students who were elected by other students as heads of the nationes, and called councillors. The coats of arms indicate the home country or city of the student, along with the student's name. On the walls of the lower portico are located a number of busts of the Seventeenth Century portraying lecturers from the University. Moreover, on the walls is also possible to notice the connection with the papal power, many are the coats of arms with the symbols of the church: triple crowns, St. Peter's keys and the clerical hats.
Anatomical Theater
The upper level of the building still houses the Anatomical theatre, which was built in 1636 by Antonio Levanti. It was the hall used for anatomy lectures and displays. It is shaped like an amphitheater and made from fir wood with a coffer ceiling, decorated with statues. It is overlooked by the ornate seat of the professor, topped by a baldaquin and supported by the statues of two naked and skinless men, known as "gli spellati", made by Ercole Lelli. The numerous sculptures that decorated the walls represent doctors from ancient and modern times: the busts are of people considered of lesser importance, while the most revered are represented in full. The two main statues, from left to right, represent Hippocrates and Galen, the most prominent physicians of Greece and Rome, respectively. Another statue on the wall opposite the chair represents a medic holding a nose in his hand: it is a portrayal of Bologna native Gaspare Tagliacozzi, an early pioneer of rhinoplasty. As a result of Allied bombings on January 29, 1944, the room suffered extensive damage, but was subsequently reconstructed with exemplary philological rigour, using all the surviving elements retrieved from the rubble.
