The Central Bethlehem Historic District, located in Bethlehem, Pennsylvania, is a site of preeminent national and international significance, representing the exceptionally well-preserved core of the communal settlement founded by the Moravian Church in 1741. Serving as the center of Moravian missionary, cultural, and industrial activity in North America, the district showcases a unique, planned community designed around the Moravian "General Economy" system. This communal social structure organized residents into "choirs" by age, gender, and marital status, which is physically manifested in the district's distinctive, German-Colonial limestone architecture. The district's extraordinary architectural and historical integrity culminated in its designation as a National Historic Landmark in 2012, and its subsequent inclusion as a UNESCO World Heritage Site in 2024, honoring its global contribution to Protestant communal planning and religious history.

Key contributing properties within the district highlight both the domestic life and the sophisticated industrial capabilities of the early Moravian settlers. Notable structures include the Gemeinhaus (1741), the oldest remaining building in Bethlehem, alongside the massive, multi-story Brethren's, Sisters', and Widows' Houses, and the monumental Central Moravian Church, completed in 1806. Along the Monocacy Creek, the district features a colonial industrial quarter, recognized as one of the earliest and most advanced industrial areas in the American colonies. This quarter includes the 1761 Tannery and the 1762 Waterworks, the latter of which is celebrated as the first pumped municipal water system in the United States. Together, these elements reflect the Moravians' remarkable synthesis of religious devotion, communal living, artistic expression, and technological innovation.
