Founded by the Bishop Eszterházy Károly, the main university building was designed by József Gerl and Jakab Fellner and built between 1765 and 1785.

 The Lyceum is held as a masterpiece of the understated Zopf Baroque style and is renowned for its three stunning ceiling frescoes.

The only one visible to everyday visitors is in the library and was painted by the Austrian Johann Lukas Kracker in 1778, depicting the Council of Trent which spearheaded the Counter-Reformation in the 1500s.
