Why it's listed

Built on about twenty acres along the Schuylkill River at East Falls, Philadelphia, the Dobson Mills complex grew from a first mill begun in 1858 into six clusters of stone buildings producing wool cloth, blankets, yarns, carpets and plush upholstery fabric. The buildings share local schist and rubble stone, heavy timber framing and arched window heads, and most are two to five stories high. Mill No. 1 produced overcoat cloth and expanded during the Civil War, when the company received large Army blanket orders. By 1890 the company is described as the largest and most diversified woolen mill in the city, with capacity near 200,000 yards of woolens per month. Early buildings reflect barn-like construction, while later additions show fire towers, toilet stacks and concrete work. The complex is regarded as a rare, largely intact record of Philadelphia mill development, with its historical importance tied to the Dobson family's role in regional textile manufacturing.

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).
