A "Foundation Stone" is a ceremonial stone that is often laid at the beginning of a construction project, symbolizing the start of building a structure. It is typically inscribed with the date of the laying and may include the names of important individuals or organizations involved in the project. This tradition is common in the construction of significant buildings, such as churches, schools, and government facilities. In addition to its ceremonial role, a foundation stone can also serve a practical purpose by providing a stable base for the structure. It is usually placed at the corner of the building and is often made of durable materials like granite or marble. The practice of laying foundation stones dates back to ancient civilizations, including the Egyptians and Greeks.
