On the upper floor of the College there is a lecture hall named after Józef Szujski &ndash; now used by historians &ndash; with the commemorative plaque in remembrance of the events surrounding Nazi German action called Sonderaktion Krakau where 183 professors were arrested and later sent to camps in Sachsenhausen and Dachau . The plaque reads : " For the freedom of spirit and service to science and nation of Jagiellonian University professors deceitfully and forcefully taken away from this hall and imprisoned by the Nazi occupant on November 6 , 1939 . " The restoration of the Neo-Gothic architectural structure took place at the end of the 20th century . It was faced with a number of challenges , notably the task of reviving the original form of the building while simultaneously improving its functionality as an educational facility . The restoration was carried out on its façade in 1994 along with the modernization of the assembly hall , which was completed in 1999 . The collaboration of specialists from various disciplines allowed for both restoration and functional needs of the Collegium to be met successfully
