Sunbury Historic District
Why it's listed
Set where the north and west branches of the Susquehanna River meet, this district covers Sunbury's traditional town square, adjacent residential blocks and the Market Street commercial corridor. The town was laid out in 1772 as one of seven proprietary towns for the heirs of William Penn, and grew from a frontier outpost into a county seat, canal port and railroad center. The district holds 264 properties, 103 individually significant and 135 contributing. Its houses include a 1773 Tilghman house, while Market Street shows Italianate, Romanesque and Second Empire commercial blocks and railroad-era hotels. The 1865 County Courthouse, designed by Samuel Sloan, reflects the town's role in government. Brick making, distilling and textile mills shaped later growth. Its significance lies in the variety of styles and the survival of upper-story fabric, which preserve the layered history of a Susquehanna Valley town.

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).
