The
Holy Royal Arch is a degree of
Freemasonry. The Royal Arch is present in all main masonic systems, though in some it is worked as part of Craft ('mainstream') Freemasonry, and in others in an
appendant ('additional') order. Royal Arch Masons meet as a
Chapter; in the
Supreme Order of the Holy Royal Arch as practised in the
British Isles, much of Europe and the Commonwealth, Chapters confer the single degree of
Royal Arch Mason.
