The witches’ place of worship isn’t like that of other religions, that have permanent consecrated places.
Witches can consecrate any area they deem suitable at any moment. That area is enclosed in a circle.
The circle, depending on the tradition and how many people will be inside it, is made in different ways. Usually it has a 9 foot diameter.
In ceremonial Magic there are three exact circles drawn, one at 9 feet, 10 feet, and the third at 11 feet.
The circle is used to keep energy built up by the witch or witches in and evil or negative forces out.
Circles can be marked by drawing a line into the earth with a sword or staff. A ribbon may be laid down, or powdered substances – usually salt can mark the circle.
There are rules that must be followed after the circle has been marked. Sometimes Wiccans refer to meeting as the “circle” because all of their rituals are done within the drawn circle.
