Hatfield-Hibernia Historic District
Why it's listed
Set along the Brandywine Creek in rural Chester County, the Hatfield-Hibernia district grew from a grist mill begun about 1738 and an iron forge established in the 1790s. Samuel Downing built the first forge, which became the Hibernia Iron Works. Charles Brooke, who bought the property in 1821, expanded the ironworks and the mansion, and he donated ground for the Hibernia Methodist Church, completed in 1841. The district is notable for its stone and stuccoed workers' houses, many dating to about 1810. Those built by Isaac Van Leer for the iron works are plain one-story cottages with nine-over-six windows. Those built by Samuel Hatfield for the grist mill are more spacious, with six-over-six windows, broad surrounds and symmetrical facades. The mill houses are believed to be the earliest surviving examples of such dwellings in the area. The iron industry declined after the Civil War and the mill closed in 1945.
Significance in brief: The district is argued to have played an important role in the industrial development of Chester County in the eighteenth and nineteenth centuries, through its water power, forges, furnaces and grist mills. Its numerous vernacular workers' houses, built by Van Leer and Hatfield in the early nineteenth century, are presented as a notable architectural record of two contrasting industrial communities side by side.

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).
