Gemeinhaus-Lewis David de Schweinitz Residence

The Moravian Museum, also known as the Gemeinhaus and the Lewis David de Schweinitz Residence, is a historic house museum at 66 West Church Street in Bethlehem, Pennsylvania. Built in 1733 to house the married couples of the Moravian community as well as the community's place of worship, the Saal, it is the oldest surviving building in Bethlehem, the largest surviving log house in the USA and also significant for its association with the botanist and mycologist Lewis David de Schweinitz (1780-1834). It was declared a National Historic Landmark in 1975.
