The institution holds two significant artifacts related to King Matthias. At the treasury exhibition, we can see the 15th-century Florentine ceremonial clothing featuring the Hunyadi Dynasty’s raven crest on its lower half. According to tradition, this was a gift to the cathedral from the king. The library’s most precious artifact is a corvina from King Matthias's renowned collection. This was the first corvina to be translated into Hungarian. Due to its sensitivity, this extremely valuable book cannot be viewed at the permanent exhibition, however, a replica was published in 2018.

One of the newest ornamental fountains in downtown Győr, the 365 kg soda siphon was created by glass-maker László Hefter of Győr.
