prøvehjørninger

Prøvehjørninger refers to a type of architectural feature specific to Nordic and Scandinavian countries, particularly in Denmark and Norway. The term translates to "trial corners" or "trial angles" in English, but the structure itself is often literally known as a "prøvehjørne" in Danish or a "prøvehøyrn" in Norwegian.

These structures are freestanding corners or angles built outwards from a main wall, particularly from a barn or a granary, to test the structure's integrity and stability. Traditionally, these corners were built at a slight outward angle from the main building, often using stone or wood, to assess the loads and stresses the construction could withstand. Initially, the aim was to secure the stability of the main building, so no unwanted structural damage would occur when specific conditions changed, such as new roof or load additions.

Construction of prøvehjørninger implied that the large exterior stone walls that were so typical of earlier construction in Denmark and Norway required the secure placement and testing of fit and stability of these vulnerable corners. Structurally, it served as an angle of deviation leading outwards and extremely indicated an increased pressure to run during constructive reproduction. These structures can be visually recognized in the rural areas of Denmark and Norway, often as freestanding stone structures, displaying an imposing presence when standing adjacent to taller buildings, especially a background around windmills and churches.

They were initially developed primarily as safety precautions for rural buildings which would outlast their authentic longevity, rather than architectural necessity.
