Foundation (engineering)
A foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures.
Cornerstone
In the Eastern Orthodox Church the blessing of the bishop must be obtained before construction on a new church may commence, and any clergyman who ventures to do so without a blessing can be deposed. The "Rite of the Foundation of a Church" (i.e., the laying of the cornerstone) will differ slightly depending on whether the church is to be constructed of wood or of stone. Even when a church is built of wood, the cornerstone must in fact be made of stone.
