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.

Keyboard instruments
All keyboard instruments have a keyboard, a row of levers that are pressed by the fingers, but they differ in their mechanics.
The clavichord has mechanics with tangents, which give it a gentle, quiet sound. The clavichord of the Ljubljana organ builder Johann Georg Eisl from 1757, so far the only known clavichord maker in Slovenia, testifies to the manufacture of this type of instrument in Slovenia.
Like the harpsichord, the spinet on display belongs to a group of instruments with a mechanism that features quills and produces a sound similar to plucked string instruments. The spinet was made in 1936 in a Baroque style.
The other instruments displayed in this room are pianos of various shapes: two table pianos, a pyramid piano, and a children’s piano. The pyramid piano was made between 1871 and 1878 by Martin Ropas from Vransko.
In the 18th century, the piano with hammer-action mechanics was invented. Within a few decades, it completely eclipsed the clavichord and harpsichord. The development and refinement of mechanics in the 18th and 19th centuries gave it excellent expressive possibilities and established it as the most widely used solo and accompanying instrument.
Feel free to try out the didactic aids on display – they demonstrate how the mechanics of different keyboard instruments work.
