An altar is any structure upon which offerings such as sacrifices are made for religious purposes. Altars are usually found at shrines, and they can be located in temples, churches and other places of worship. Today they are used particularly in Christianity, Buddhism, Hinduism, Shinto, Taoism, as well as in Neopaganism and Ceremonial Magic. Judaism did so until the destruction of the Second Temple. Many historical faiths also made use of them, including Greek and Norse religion.
