***************************
An altar is a structure upon which offerings such as sacrifices are made for religious purposes. Altars are found at shrines, temples, churches and other places of worship. They are used particularly in Christianity, Buddhism, Hinduism, Judaism (until the destruction of the Second Temple), and Modern Paganism. Many historical faiths also made use of them, including Roman, Greek and Norse religion.
