A tabernacle or a sacrament house is a fixed, locked box in which the Eucharist is stored as part of the "reserved sacrament" rite. A container for the same purpose, which is set directly into a wall, is called an aumbry.

The Tridentine Mass, also known as the Traditional Latin Mass or the Traditional Rite, is the liturgy in the Roman Missal of the Catholic Church codified in 1570 and published thereafter with amendments up to 1962. Celebrated almost exclusively in Ecclesiastical Latin, it was the most widely used Eucharistic liturgy in the world from its issuance in 1570 until the introduction of the Mass of Paul VI.
A pre-1969 Roman-Rite high altar decorated with reredos and set on a three-step platform, below which the Prayers at the Foot of the Altar are said. Leaning against the tabernacle and two of the candlesticks are altar cards, to remind the celebrant of the words when he is away from the missal.
