Builders' rites

Builders' rites are ceremonies attendant on the laying of foundation stones, including ecclesiastical, masonic or other traditions connected with foundations or other aspects of construction.

One such custom is that of placing a few coins, newspapers, etc. within a cavity beneath the stone. Should the stone later be removed, the relics may be found. Though this tradition is still practiced, such memorials are deposited in the hope that they will never be disturbed.
