The Province of Bedfordshire, Cambridgeshire and Hertfordshire was constituted on Thursday, 8 March 1990 at the Masonic Hall, Rosewalk, Radlett, Herts. The Meeting commenced at 12.30 p.m.

The Ceremony was carried out by the then Grand Supreme Ruler, M.Wy.Bro. Lt. Col. John Walter Chitty MBE, assisted by Officers of Grand Conclave.
