Mill Creek Historic District (Boundary Increase)
Why it's listed
Along Mill Creek in Lower Merion Township, a wooded ravine about ten miles from central Philadelphia holds a cluster of water-powered mills, mill workers' houses and mill ruins dating from the eighteenth and nineteenth centuries. The creek's fall of roughly 250 feet made it a valuable source of power, and the earliest recorded mill was built by John Roberts. Christopher Robins constructed a mill here in 1758, and the Walover/Jones Mill complex, possibly dating to the same year, is the most intact of the mill communities. Paper was the main product in the eighteenth century, and later mills turned to gunpowder, lamp wicks, textiles and gun parts. Nippes began making long guns here in 1814. The district is also significant for its large estate houses and twentieth century residences, and for archaeological sites that may show how mill workers and owners lived.
Significance in brief: The document argues the district is important for its role in the milling industry, which produced paper, guns and textiles and helped make the Philadelphia region a center of industry, and for its archaeological sites. It is also significant architecturally for its mill complexes, large turn-of-the-century estate houses and 1920s to 1940s residences by architect Walter K. Durham.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
