THE COLLECTION OF ARMS at Ptuj Castle is of national importance, as it comprises more than 500 pieces of various cold weapons, firearms, hunting and sporting weapons, and protective equipment dating from the 15th to the 20th centuries. Most of the exhibited items come from the nearby Vurberk Castle, while some pieces were collected by members of the Ptuj Museum Society.

Heritage of the Ptuj Military Band
Ptuj has a long tradition of having city musicians. In the late Middle Ages, the town already had a Civic Guard with instrumentalists.
The oldest depiction of the Civic Guard Band, which shows five musicians playing around a table, dates from 1815. A copy of the relief can be seen as part of the recreated beer hall in the left-hand corner of the room. The life-size soldier is a drummer of the military brass band from around the same time.
The displayed instruments were made by renowned masters from Vienna and Graz in the 18th and 19th centuries.
An especially noteworthy instrument is the bass horn, a curious instrument used mainly in military brass bands. Its lower part resembles a bassoon and its upper part a horn.
The military snare drum from 1759 features a German inscription on the edge of the lower membrane. It reads that in 1809, the sounds of a French march from this drum drove the Austrian troops from the Croatian border.
