Ralph G. Schwarz Center for Colonial Industries / Grist Miller’s House Restoration
Location: Bethlehem, PA
Client: Historic Bethlehem Museums and Sites
Date Completed: 2025
Artefact was hired to design the restoration/retrofit of the Grist Miller’s House, which sits adjacent to the 1869 Luckenbach Mill in the Colonial Industrial Quarter of Historic Moravian Bethlehem’s (PA) National Historic Landmark District.
This original stone masonry house (1782) was one of the earliest private Moravian family homes in America. In 1834, a two-story brick expansion added a family living floor and a second story with bedrooms and an attic above, becoming one of the first examples of an expansion of a miller’s living quarters during this period.
Part of the Moravian Church Settlements that were inscribed in 2024 as a UNESCO World Heritage Site, the Colonial Industrial Quarter is considered one of America’s first industrial parks. Despite the historical significance of the Mill and Miller’s House (the latter an individually listed National Register property), these properties suffered decades of neglect after mill operations ceased in the 1940s. The Mill was repurposed as an auto parts store and its grounds devolved into an unsightly junkyard until cleanup/restoration efforts began in the 1980s. While the Mill was fully restored and converted into a multipurpose space at this time, the Miller’s House remained neglected until the present project.
Returned to its historic appearance but updated for safety and accessibility, code compliance, and modern utility, the restored Miller’s House is the final jewel in the crown of the revitalized Colonial Industrial Quarter. It has also been retrofitted for a long-anticipated new use: to house a venue for education on colonial trades and crafts in honor of Ralph G. Schwarz, a leading advocate for historic preservation. The Schwarz Center/Miller’s House is now open to the public for the first time in decades, returning this special building to the realm of living history with renewed purpose.
