The Provincial Grand Master's Lodges of Instruction are held monthly at the Watford, Cheshunt and St Albans Masonic Centres.

Further information on the Lodges of Instruction is detailed within this website.

All Mark Master Masons and Royal Ark Mariners within the Province of Hertfordshire are eligible to attend and will be welcomed. The purpose of the Provincial Grand Master's LOI's is to support members who currently hold office or are progressing into an office in their Lodge. Past Masters who wish to refresh their own skills and assist in ceremonial rehearsals will also be most welcome.

The Lodges of Instruction are able to facilitate the rehearsal and practice of all aspects of the Mark and Royal Ark Mariner ritual and ceremonies. In so doing they support the Right Worshipful Provincial Grand Master in his drive to continue the improvement of ritual, and the standard of ceremonies throughout the Province.
