The collections of Gothic and Baroqueart are exhibited in two rooms on the second floor of the castle. The gallery exhibits works donated to the museum by Professor Franz Ferk, and also works from churches and castles of Ptuj and its environs.

Among the Gothic works of art, most precious is a group of sculptures from the ťPtujska gora workshopŤ. The Saints Barbara and Catherine, both from around 1410, are masterpieces of contemporary sculpture in Europe.

The Baroque paintings from the 17th and 18th centuries show attractive vedutas of Ptuj Castle and the town in the past, a banquet, two landscapes, and biblical and mythological scenes.
