Central Norristown Historic District
Why it's listed
Norristown's central district lies on a hill and valleys north of the Schuylkill River and combines the Montgomery County courthouse square, the borough's Main Street business district, mills, churches and housing in one connected area of roughly forty blocks. Its development follows county government from 1784, when the county was formed and a 27 1/2 acre seat was set aside, and the borough's growth after its 1812 incorporation. Industry grew along Stoney Creek and Saw Mill Run, served by the Schuylkill Canal, the Reading Railroad and trolley lines from the 1880s. The district holds Greek Revival houses, Italianate villas and rows, and late Victorian mansions, including the 1849 Corson-Highly House and the 1893 McInnes House. Its architecture is cited as evidence of the town's economic and ethnic diversity, and the district's buildings have largely kept their original form.
Significance in brief: The district is presented as an intact example of a 19th and early 20th-century Pennsylvania industrial county seat, combining county government, a borough business district, industry, and varied residential neighborhoods. Its architectural diversity is said to reflect the town's economic, ethnic and social diversity, and its architectural integrity is described as a key part of its importance.

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).
