Housed in Bethlehem's 1741 Gemeinhaus — believed to be the largest 18th-century log structure in continuous use in the United States and a National Historic Landmark — the Moravian Museum introduces visitors to the earliest history of the Bethlehem community. The building originally served as home, church, and classroom to the Moravian settlers who founded the city, and it now anchors the Moravian Church Settlements–Bethlehem World Heritage Site. For private events, the museum opens its Saal, the community's first place of worship, where vows have been exchanged since colonial times. The Saal accommodates up to 60 guests seated for a reception or 80 for a ceremony or theater-style gathering, while the Gemeinhaus overall holds up to 100 people. Hosts can extend the occasion with a personalized group tour of the museum, part of Historic Bethlehem Museums & Sites' network of historic rental venues.
