Freemasonry is one of the world's oldest secular fraternal societies. The following information is intended to explain Freemasonry as it is practised under the United Grand Lodge of England, which administers Lodges of Freemasons in England and Wales and in many places overseas.

The explanation may correct some misconceptions. Freemasonry is a society of men concerned with moral and spiritual values. Its members are taught its precepts by a series of ritual dramas, which follow ancient forms, and use stonemasons' customs and tools as allegorical guides.
