Masonic Landmarks

Masonic landmarks are a set of principles that many Freemasons claim to be ancient and unchangeable precepts of Masonry. Issues of the "regularity" of a Freemasonic Lodge, Grand Lodge or Grand Orient are judged in the context of the landmarks. Because each Grand Lodge is self-governing, with no single body exercising authority over the whole of Freemasonry, the interpretations of these principles can and do vary, leading to controversies of recognition. Different Masonic jurisdictions have different landmarks.
