In Britain, separate bodies administer each order. Freemasons are encouraged to join the Holy Royal Arch, which is linked to Mark Masonry in Scotland and Ireland, but completely separate in England. In England, the Royal Arch is closely associated with the Craft, automatically having many Grand Officers in common, including H.R.H the Duke of Kent as both Grand Master of the Craft and First Grand Principal of the Royal Arch. The English Knights Templar and Cryptic Masonry share the Mark Grand Lodge offices and staff at Mark Masons Hall.
