An altar representation of a mountain top, which is where the gods dwelt and where humanity when to speak to them. It can be any raised flat surface used for performing ritual. It can be a table, a flat rock, a flat tree stump, or an intricate carved marble altar. The ancient Jews piled uncut stoned, usually 12, and did their rituals atop the pile. . 

Many Witches do not have a separate altar, but use the top of some ordinary piece of furniture as an altar. When this is done, there is usually a special altar cloth that is laid over the furniture top during the perfomance of ritual.

Exactly what goes on the altar varies by Witchcraft tradition. Trasitionally there is a cup, an athame, a rod and a pentacle.Some common elements include: candles, a bowl of water, salt, incense (and incense holder or censor), a statue or picture of a gods or goddess (either gods or goddesses related to the specific ritual being performed, or gods or goddesses that are special to you), flowers, berries, crystals and rocks, leaves, twigs, just about anything natural, wine glass (and ceremonial wine), representations of the elements (earth, air, water, and fire, for most Western traditions, or the five Chinese elements of metal, water, wood, fire, and earth), a ceremonial knife (called an athame), a wand, any ingredients for the rituals or spells to be performed, any special tools of your Witchcraft tradition, and anything that you feel helps connect you to the divine or to Witchcraft.

Some Witches set up a shelf or furniture top as a permanent altar setting. They may place a temporary flat surface in front of the permanent altar setting when using the altar. Or they might leave open space for this purpose in front of the permanent setting.

The permanent altar setting becomes a full time display honoring nature, the Lord and Lady, or anything else of interest to the Witch. Some Witches enjoy working on a permanent altar setting as a hobby or as artistic expression, continually refining it or changing it to match the wheel of the year.

Some Witches can’t have a permanent altar setting (disapproving parents, pets, small children, etc.) and other Witches prefer to keep their magick more personal and out of public display.

In the Burning Times, Witches had to either cleverly hide permanent altars as just “displays” or had to use only temporary altars.

Whether permanent or temporary or some combination of both, the altar becomes a personal expression of your spirit, your spirituality, and your magick. Your altar should be both decorative and functional. Your altar should “feel right” to you.

Many Witches cast a circle before they work on their altar.
