When the first waves of Dutch, British, and Scottish settlers arrived in Ulster County, they brought with them more than tools and ambitions — they brought their lodges. Freemasonry functioned as a kind of invisible architecture of colonial and early American society: a fraternal system that gave immigrant communities a framework for trust, civic participation, and shared identity in an unfamiliar world. In this program, author and researcher Glenn Kreisberg explores the esoteric origins and local history of Freemasonry in Ulster County — who established the lodges, what principles guided them, and how they shaped the communities that formed around them.
