The Moravian Historical Society is a nonprofit museum and historic site that preserves, interprets, and celebrates the rich culture of the Moravians. Located in Nazareth, Pennsylvania, we maintain the 1740–1743 Whitefield House and the 1740 Gray Cottage, the oldest surviving Moravian structure in North America. Recognized widely for its significant collection and historically important 18th-century site, the Moravian Historical Society is the third oldest historical society in Pennsylvania.
