The story that haunts this land
Your quest begins in front of the Central Moravian Church, at 73 West Church Street. This Georgian edifice, built between 1803 and 1806, was the spiritual heart of Bethlehem's Moravian community, designated a National Historic Landmark in 1970. Its 100-foot (30 m) tall steeple and 1832 organs still echo with the hymns of the settlers. It is here, in the center of the historic district founded in 1741, that the first clues of your GPS scavenger hunt await, revealing the perseverance of the Moravians in Pennsylvania.
Continue to the Gemeinhaus, the oldest poured concrete building in North America, erected in 1741 and designated a National Historic Landmark. Measuring 108 feet (33 m) long, it served as a communal home for the first 25 Moravian settlers, housing a church, school, and living quarters until 1744. This historic site in Bethlehem bears witness to the colony's beginnings and the strict organization of Moravian life, a key step in understanding Bethlehem's heritage.
Your journey then leads you to the Single Brethren's House, at 66 West Church Street, erected in 1785. This three-story stone building housed the unmarried brothers of the community, with workshops and dormitories for up to 30 residents. Listed on the National Register of Historic Places in 1971, this monument in the Historic Moravian District illustrates the social and economic life of the Moravians, an important aspect of Bethlehem's history.
The Moravian Cemetery, or God's Acre, established in 1742 and located about 0.5 km away, reveals one of the oldest Moravian cemeteries in the USA. Its flat, uniform graves symbolize equality, a fundamental principle of the Moravian faith. This 3-acre (1.2 ha) site contains over 4000 burials, including those of Bethlehem's founders. Each stone is a chapter of Bethlehem's history, and your interactive visit will allow you to decipher the secrets of this community.
The Sun Inn, opened in 1735 as a tavern and rebuilt in 1782 after a fire, at 564 Main Street, will immerse you in the social life of colonial Bethlehem. George Washington stayed here in 1782 and 1793, and the edifice was designated a National Historic Landmark in 1981. This 14-room stone building was a central hub. By exploring this thematic circuit, you will have discovered places like the Moravian Blacksmith Shop from around 1761, the 18th-century Bell House, and understood the importance of Bethlehem, Pennsylvania, in American history, far beyond classic guides.
