An altar is an elevated and consecrated place used during worship in many religions. It may take many forms, including a movable table in the front of a church or a shrine built into the walls of a temple. Objects with particular religious importance are often kept on or around the altar, including offerings and relics. During religious ceremonies, worshipers face the altar and the religious officiant who is guiding the ceremony.
