From the 15th century, on the ground floor, apart from utility rooms and a few professors’ dwellings, there were also lecture rooms, which were named in honour of the great philosophers of antiquity and patrons of science, including Galen, Socrates, Pythagoras, Ptolemy, Plato and Maron (Virgil). In this way, the continuum of the teaching tradition since Greek and Roman times was emphasized. Most likely at the beginning of the 16th century, the lecture rooms were enriched with solid vaults because the entire structure of the building was erected above them. Classes took place in the lecture rooms until Hugo Kołłątaj’s reforms. The lecture room which housed the old offices was called the Socrates lecture room. From there you could enter the Hippocrates lecture room, where in the 17th and the 18th centuries, the paper warehouse of the University printing house was located.

Currently, in the former lecture rooms, temporary exhibitions are held, usually in the fields of art history or painting. Some exhibitions are also related to the history and contemporary activities of the Jagiellonian University. The rooms can be visited during temporary exhibitions only.
