Tabernacle

A tabernacle, also called a sacrament house, is a fixed, locked receptacle, usually located in a church or chapel, in which the Eucharist is reserved as part of the practice of keeping the "reserved sacrament". The word tabernacle means "dwelling place", which now refers to the place where "Christ dwells in the Eucharist". A container for the same purpose that is set directly into a wall is called an aumbry and has historically been used in this way in Western churches.
