The Lodge of Trinity College Cambridge was Consecrated on 30th March 1939, sponsored by an existing Cambridge college Lodge, Lady Margaret. Since then, it has met on the second Thursday in November and February and the first Thursday in May, in London. The early meetings of the Lodge were overshadowed by the war years, and the Lodge remained a small band of brethren through this period. A period of consolidation took place after the war, and in 1964, the practice of holding an emergency meeting in college was introduced. This has been a delight to members, thanks to the tolerance of the college.
A Lodge History was produced in 1989, recording the first Fifty Years of the Lodge's working. A "pdf" is available here.
Members of the Lodge of Trinity Cambridge have a dispensation which allows the wearing of a college tie, rather than the customary black tie, and gloves are not worn.
The Lodge of Trinity, Cambridge has remained a closed Lodge, with membership restricted to men who are members of the College or their close family and are over the age of 21. Whilst this has restricted the number of possible members, it has given the Lodge an unique sense of cameraderie. Members come to meetings from all over the country and even from abroad.
The annals of the Lodge record an appreciable number of Freemasons of Grand Rank.
The Lodge of Trinity, Cambridge practices Emulation Ritual; however, having eminent Freemasons from all around the country, aspects of alternative workings are often introduced into presentations, to give an unique blend of ritual: 'Trinity Working'.
The Lodge has a tradition of musical presentations at the aftermeetings, and sometimes during meetings.
