Kaisersteinbruch Stonemason museum, Stonemasonry museum in Bruckneudorf, Austria.

Kaisersteinbruch Stonemason Museum displays tools, machinery, and objects from the history of stone extraction and processing in Austria. The collection documents local craftsmanship traditions and their techniques in detail.

The collection was established through a teacher's initiative in the 1990s and preserves the memory of craftspeople who faced displacement in the early 20th century. This institution safeguards records about the importance of the local stone industry to the region.

The museum keeps the Kaisersteinbruch stonemasons' guild traditions alive: the 'Freisprechbuch' records apprentices being released as journeymen before the open chest, and copies of the guild's handwerksordnung can be studied. The 1617 Viertellade of the Wiener Neustädter Bauhütte covered market towns from Sommerein to Jois, and the annual stonemason gathering continues this craft identity.

The museum occupies one room of the former two-class school in Kaisersteinbruch, in the municipality of Bruckneudorf. The exhibition is arranged around a central lapidarium, with display cases along the walls. The room still holds school desks from the 1920s, some with recessed inkwells, so space between rows is narrow.

The museum houses an original document from the 17th century proving the independence of the local stonemason guild. This record shows how self-governed this trade was and its importance within the building industry.
