Westmoreland County is located just east of Pittsburgh in southwest Pennsylvania. It’s a big one. In fact, it’s the second largest county in Western Pennsylvania by area.
The landscape’s a mix of rolling hills and river valleys. There’s a lot of history here. Fort Ligonier played a key role in the French and Indian War. These days, it’s more about industry and suburbs.
Greensburg is the county seat. The old Pennsylvania turnpike runs right through. You’ve got some great parks, like Laurel Ridge State Park. Arnold Palmer, the golf legend, grew up in Latrobe. The county has a good balance of town and country living.
