Cornerstone

The cornerstone (or foundation stone or setting stone) is the first stone set in the construction of a masonry foundation. All other stones will be set in reference to this stone, thus determining the position of the entire structure. Some cornerstones include time capsules from, or engravings commemorating, the time a particular building was built.
