History of the Trestleboard
Historically, a trestleboard was a board upon which ancient stonemasons sketched designs and architectural plans before building. In modern Masonic usage, it serves a similar function—a Trestleboard is often a newsletter or bulletin issued by a lodge to inform members of upcoming meetings, events, degrees, and other important matters. It can also contain messages from the Worshipful Master, his pillars, lodge officers, and educational content.
