Blue Lodge

A Masonic lodge, often termed a private lodge or constituent lodge, is the basic organisational unit of Freemasonry. It is also commonly, but erroneously, used as a term for a building in which such a unit meets. Every new lodge must be warranted or chartered by a Grand Lodge, but is subject to its direction only in enforcing the published constitution of the jurisdiction. By exception the three surviving lodges that formed the world's first known grand lodge in London (now merged into the United Grand Lodge of England) have the unique privilege to operate as time immemorial, i.e., without such warrant; only one other lodge operates without a warrant – the Grand Stewards' Lodge in London, although it is not also entitled to the "time immemorial" title. A Freemason is generally entitled to visit any Lodge in any jurisdiction (i.e., under any Grand Lodge) in amity with his own. In some jurisdictions this privilege is restricted to Master Masons (that is, Freemasons who have attained the Order's third degree). He is first usually required to check, and certify, the regularity of the relationship of the Lodge – and be able to satisfy that Lodge of his regularity of membership. Freemasons gather together as a Lodge to work the three basic Degrees of Entered Apprentice, Fellowcraft and Master Mason.

Technically, Freemasons meet as a lodge not in a lodge. In this context, the word "lodge" refers to a local chapter of Freemasons, meeting as a body. However, the term is often misused to refer to the buildings or rooms that Mason's meet in. Masonic premises are also sometimes referred to as temples ("of Philosophy and the Arts"). In many countries Masonic centre or Masonic hall has now replaced these terms to avoid arousing prejudice and suspicion. Several different lodges, or other Masonic organisations, often use the same premises at different times.

Blue lodges, craft lodges or ancient craft lodges refer to the lodges that work the first three Masonic degrees, rather than the appendant Masonic orders such as York Rite and Scottish Rite. The term "craft lodge" is used in Great Britain. The blue lodge is said to refer to the traditional colour of regalia in lodges derived from English or Irish Freemasonry. Although the term was originally frowned upon, it has gained widespread and mainstream usage in America in recent times.
