põhikiviks
Põhikiviks is an Estonian term that translates to "cornerstone" or "foundation stone." It refers to the first stone laid in the construction of a building, often marking the beginning of the project. Historically, the placement of the põhikiviks was a significant event, sometimes accompanied by ceremonies and blessings. This stone served not only as a structural element but also as a symbolic representation of the building's stability and permanence. In some traditions, the põhikiviks would contain a capsule with a document detailing the building's purpose, the names of those involved in its construction, and sometimes even current coins or other artifacts. This practice was intended to preserve a record of the building's origins for future generations. While modern construction techniques may have altered the literal importance of a single "foundation stone," the concept of a põhikiviks endures in a more metaphorical sense, representing the core principles or initial impetus behind a project, idea, or organization. It signifies the essential element upon which everything else is built.
