Knights Templar (Freemasonry)
Local bodies of Knights Templar are known as Preceptories; local bodies of Knights of St Paul are known as Chapters; local bodies of Knights of Malta are known as Priories; all operate under a Grand or Great Priory, often with an intermediate level of Provincial Priories. Although some jurisdictions maintain a separate Great Priory of the Temple and Great Priory of Malta (as, for example, in England), the Grand Master and other officers of both Great Priories hold simultaneous equal office in both bodies. Three degrees are administered in this system:In England and Wales, the "Great Priory of England and Wales" for the Masonic Knights Templar is administrated from Mark Masons' Hall, London.
