Thornton Village Historic District
Why it's listed
Centered on a T-shaped crossroads in western Thornbury Township, Delaware County, Pennsylvania, the Thornton Village Historic District holds fifteen buildings, thirteen of them contributing, built mostly between 1790 and 1855. The anchor is the Yellow House, a two-story Penn Plan dwelling begun about 1750 as an inn on the Great Road. It later served as a general store, cloth manufactory and post office. The village grew around it, with a blacksmith shop, residences and stables clustered along Glen Mills Road. The post office was established there in 1829 and has operated in the building since 1878, and it is regarded as one of the oldest post offices in its original location in the United States. The district is also associated with the Battle of the Brandywine in 1777, when fleeing American troops passed the Yellow House. Its surviving buildings preserve a rural village layout that was little changed after 1860, when the village was bypassed by main roads and railroads.

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).
