ALTAR

An Altar is an elevated place or structure before which religious ceremonies may be enacted or upon which sacrifices may be offered. It is a structure, typically a table, before which the divine offices are recited and upon which the Eucharist is celebrated in Church. The altar was usually placed in a chapel from where it could be seen by all the worshipers.
