Kulmakaari

Kulmakaari is a Finnish term that translates to "corner stone" or "corner arch." It refers to a specific architectural element used in building construction. Typically, a kulmakaari is a curved or angled piece that forms the internal corner of a structure, providing structural support and aesthetic finishing. These elements are often found in older buildings, particularly in traditional Finnish wooden architecture.

The function of a kulmakaari is multifaceted. Structurally, it helps to brace the corner, preventing the walls from splaying outwards. It also distributes the load from the upper parts of the building to the corner posts or foundation. Aesthetically, the kulmakaari can be left plain or ornamented, adding a decorative detail to the interior. In some cases, the size and shape of the kulmakaari could indicate the status or age of the building. The materials used for kulmakaari vary, but wood is most common, reflecting the prevalent building materials in Finland. While less common in modern construction due to changes in building techniques and materials, the kulmakaari remains a significant feature in understanding historical Finnish building practices and vernacular architecture.
