The term "Blue Lodge" refers to the foundational level of Freemasonry, a fraternal organization that promotes moral and ethical development among its members. It typically consists of three degrees: Entered Apprentice, Fellow Craft, and Master Mason. These degrees introduce members to the principles of Freemasonry, including brotherhood, charity, and integrity. Blue Lodges are local chapters where Masonic meetings and rituals take place. They serve as the primary setting for members to gather, learn, and participate in various activities. Each lodge operates under a charter granted by a larger governing body, often referred to as a Grand Lodge.
