Perustuskivi

Perustuskivi is a Finnish term that translates to "foundation stone" or "cornerstone." In architecture and construction, it refers to the first stone laid at the base of a building's foundation. This stone is often chosen for its durability and significance, as it bears the initial weight of the structure and symbolizes the commencement of the building project.

Historically, the placement of a perustuskivi was a ceremonial event. It often involved inscriptions or hidden time capsules containing documents, coins, or other artifacts meant to commemorate the building's construction or to imbue it with good fortune. The precise location and setting of the perustuskivi could vary depending on tradition and the specific architectural design of the building.

In modern construction, while the ceremonial aspect may be less common, the concept of the foundation stone remains critical. It signifies the starting point of the structural integrity of a building. Engineers and builders meticulously select and position the foundation stones or concrete footings to ensure the stability and longevity of the entire edifice. The term "perustuskivi" thus encapsulates both a practical construction element and a symbolic marker of beginnings.
