kulmakiveä
Kulmakiveä is a Finnish term that translates to "cornerstone" or "foundation stone." Historically and architecturally, it refers to the stone placed at the corner of a building, often the first stone laid during construction. This placement is significant as it helps define the angle and stability of the entire structure. In many cultures, the laying of the cornerstone was accompanied by ceremonial events and was believed to bring good fortune to the building and its occupants. The kulmakiveä could be a specially chosen or carved stone, sometimes bearing inscriptions or dates. Beyond its literal architectural function, the term "kulmakiveä" is also used metaphorically. It represents something fundamental, essential, or the basis upon which something larger is built, whether it be an idea, an organization, or a relationship. In this figurative sense, the kulmakiveä signifies the critical element that provides support and structure.
