Mill Creek Historic District
Why it's listed
Mill Creek runs through a wooded valley in Gladwyne, Lower Merion Township, about ten miles from central Philadelphia, and this district grew around a milling settlement begun by Welsh Quaker miller John Roberts, who set up a grist mill called The Wain by 1690. The surviving houses are built of locally quarried rubble stone, several stuccoed later, with porches, pent eaves and steep roofs that reflect Welsh and English Quaker building traditions. The house at 105 Old Gulph Road was built in stages from about 1720 to 1752 by Roberts and his son, and it records changing scale and finish over time. Other features include a mill store dated 1771, a stone house dated about 1750, and the ruins of three mills, including Conrad Sheetz's 1748 paper mill and Samuel Croft's 1846 brass and copper rolling mill. The milling complex is regarded as one of the early industrial developments in Lower Merion.
Significance in brief: The district is argued to be significant for its concentration of Welsh Tract and Quaker vernacular stone architecture of the 1700s, and for its role in the early milling and paper industries along Mill Creek. The remains of three mill sites and the milling village arrangement of mill owner's house, mill store, mills and millworkers' housing are presented as evidence of Colonial industrial life.

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).
