Allegheny County Courthouse
The Allegheny County Courthouse in Downtown Pittsburgh, completed in 1888, is the centerpiece of a complex that also includes the old Allegheny County Jail, both designed by Henry Hobson Richardson. Considered among the finest examples of the Romanesque Revival style that bears his name, Richardson himself called it his 'great achievement.' It was designated a National Historic Landmark in 1976.
