Quatuor Coronati


Quatuor Coronati Lodge is the world’s premier research lodge. Established in 1884 and consecrated in 1886, the lodge champions an evidence-based approach to the study of Masonic history and research into the origins of Freemasonry. It was then and is now referred to as the ‘authentic school’.
Quatuor Coronati shares its research and provides support to Masonic researchers internationally through the QC Correspondence Circle (‘QCCC’), established more than a century ago.

  • We hold meetings incorporating lectures five times a year at Freemasons’ Hall in London, to which all QCCC members are welcome;
  • publish our lectures, research papers and ‘notes & queries’ annually in Ars Quatuor Coronatorum, ‘AQC’, the Transactions of the Lodge, which is distributed worldwide to QCCC members and libraries;
  • make available scarce and valuable works on Freemasonry;
  • provide lecturers and speakers nationally and internationally; and
  • arrange conferences and symposia on different aspects of Freemasonry.

If you would like to become involved in the activities of Quatuor Coronati Lodge the first step is to join QCCC, which is open to everyone interested in Masonic research.
Details of how to join and forthcoming events, including our 2018 US Conference, are available online at
