The Allegheny County Courthouse in Downtown Pittsburgh, is part of a complex (along with the old Allegheny County Jail) designed by H. H. Richardson. The buildings are considered among the finest examples of the Romanesque Revival style for which Richardson is well known.
The complex is bordered by wide thoroughfares named for city founders James Ross (Ross Street), John Forbes (Forbes Avenue) and James Grant (Grant Street). The current building, completed in 1888, was designated a National Historic Landmark in 1976. Richardson later referred to it as his "great achievement".
