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.

Pole weapons
On the left side of the armoury, pole weapons are displayed: spears and lances, halberds, corseques, partisans, spontoons, battle axes, and maces.
The pole increased the power of a soldiers swing and stab. Lances were mainly used by cavalrymen, while spears were used by the infantry when trying to stop a cavalry charge. These weapons also protected marksmen during the time-consuming reloading of their rifles.
The halberd evolved from the battle axe, to which a hook and spike were added. It was used from the 14th to the 16th century for hacking, stabbing, and catching with the hook. In the second half of the 16th and in the 17th century, it was mainly a weapon of guardsmen and trabants. Many halberds from this era are decorated with beautiful ornamentation.
