32 Masonic Symbols & Their Meanings

A complete illustrated guide to the most important symbols in Freemasonry

Freemasonry communicates its core teachings through a rich system of symbols drawn from the tools of operative stonemasons. Each symbol carries layered meanings that Masons study throughout their journey from Entered Apprentice to Master Mason and beyond. This guide covers the 32 most important Masonic symbols, their origins, and what they mean to Freemasons today.
