in architecture, is that part of a building which is under-ground. See Architecture, n° 96 et seq. and n° 136 &c.
Palladio allows a sixth part of the height of the whole building for the hollowing or under-digging, unless there be cellars under-ground, in which case he would have it somewhat lower.
**Foundation**, denotes also a donation or legacy, either in money or lands, for the maintenance and support of some community, hospital, school, &c.
The king only can found a college, but there may be a college in reputation founded by others. If it cannot appear by inquisition who it was that founded a church or college, it shall be intended that it was the king, who has power to found a new church, &c. The king may found and erect an hospital, and give a name to the house upon the inheritance of another, or license another person to do it upon his own lands; and the words fundo, creo, &c. are not necessary in every foundation, either of a college or hospital, made by the king; but it is sufficient if there be words equivalent: the incorporation of a college or hospital is the very foundation; but he who endows it with lands is the founder; and to the erection of an hospital, nothing more is requisite but the incorporation and foundation.
