The Apse: The curved area behind the altar where the tabernacle is located in many churches.
The Altar: The sacred table on which the sacrifice of the Mass is offered to God; the table from which the faithful receive the Blessed Sacrament.
The Ambo: The lectern from which the readings are proclaimed.
