Anything in the Pittsburgh metro built between 1720-1840 is fair game for this thread. I originally thought this might be difficult since Pittsburgh is so noted for being a Victorian-era city, but scouting out these areas, I found there is much more Georgian-period architecture in the area that I could reasonably expect to photograph.
The first piece is one of the oddest and most interesting houses I've found in the area. The core of the structure was built somewhere in between 1815-1835 with the wings added sometime before the Civil War. It is located in Scenery Hill, PA.
Ambridge, PA--1820s: There are about 80 of the small brick houses scattered around the town; many are in disrepair while others are bought by private investors.
Old Economy Village is the part of Ambridge, PA that is owned by the state and fenced off from the rest of the city. Like above, most structures are from the 1820s.
The Bradford David House in Washington, PA was built in 1788 and was the home of the Whiskey Rebellion.
The LeMoyne House was built in 1812 in Washington, PA and is one of only 6-8 Historic Landmarks in the country marking the Underground Railroad.
I don't know the name of this house in Freedom, PA, but it was built on the Ohio River in the 1830s by a Philadelphia sea captain.
This building is now the Western PA Conservancy and was built in the 1830s. It is in Downtown Pittsburgh and is Greek Revival.
These buildings are from Washington and Jefferson University. The first, Old Main was built in the 1831 (center building). The other building is from 1793, is Greek Revival. The wings of the latter were added in 1816, also Greek Revival.
This house in the Hazelwood neighborhood of Pittsburgh was built in the 1790s and is obviously under repair.
The Brush Hill Home in Irwin, PA was built in 1798 and was the first "mansion style" house west of the Allegheny mountains.
I don't know if this house is old or not, but it looks old and was very close to the last house!
The Fort Pitt Blockhouse is the oldest extant structure in the city of Pittsburgh and I believe it may be the oldest west of the Allegheny Mountains. It was built in 1764.
This is the Century Inn or Hill's Tavern in Scenery Hill, PA. It was built in 1794 and has operated as a restaurant continuously for 214 years.
Hope you enjoyed it! I leave you with the bonus pic of Primanti Bros. downtown.
