The 1741 Gemeinhaus, Bethlehem’s oldest building and a National Historic Landmark, houses a museum that tells the stories of the Moravian founders. Opening the herringbone-patterned doors of this five-story log structure, the largest 18th century log building in the United States, reveals a place which served as home, school, church, and workspace during the community’s earliest days. The museum complex also includes the 1752 Apothecary, or drug store, and the 1758 Nain-Schober House, the only remaining 18th century residence for Christianized American Indians in eastern Pennsylvania, currently undergoing restoration.
