Shaw Historic District
Also known as: Francis B. Shaw Block Historic District
Why it's listed
Along South Main Street in Doylestown, a block of lots laid out in 1830 from Francis B. Shaw's Underhill Farm still shapes the streetscape. Houses of two and a half to two and three-quarter stories, mostly built between 1832 and the 1870s, sit close to the sidewalk on long, narrow lots that run back toward South Clinton Street. The block became the site of the Doylestown Agricultural Works, founded in 1849 and making threshers, horsepowers and farm machinery sold across the United States and abroad. Its Doylestown Thresher won first prize at the Philadelphia Exposition of 1876. The Works was rebuilt in brick after a fire in December 1913 and operated until 1968. Nearby stood a livery stable, a railroad hotel and a hardware store, which show how the block served local commerce after the railroad arrived in 1856. The nomination values the group for its conservative architecture, its industrial history and its record of early town growth.
Significance in brief: The district is significant for its link to the Doylestown Agricultural Works, a manufacturer of threshers and farm machinery that the nomination says had national and international reach. It is also significant for its conservative mid-19th-century architecture and for the pattern of narrow lots laid out in 1830 by Francis B. Shaw, which the nomination ties to the town's commercial growth.

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).
