The lodge owes its existence to a group of masons who regularly met once a week at the Station Hotel, Knebworth. Sponsored by the Knebworth Lodge No. 6941, Fairlands Valley Lodge was consecrated on 6th October 1973, with twenty-three founder members and five original members by VW Bro Guy Halsey, TD, PJGD, Deputy Provincial Grand Master. Because the majority of the founders were from the Stevenage area, the lodge was given the name Fairlands Valley, after a particular beauty and recreational area located within the New Town.
The lodge banner, which depicts the Fairlands Valley park and a sailing boat, mysteriously numbered J9, together with a ladder behind the emblem with an anchor and gold cup, and was dedicated on 2nd May 1977 by RW Bro Guy M Halsey, then Provincial Grand Master. The lodge continues to meet at the Cloisters, Letchworth.
