The County Office Building, which opened in 1931, was designed by Stanley L. Roush, who was the king of public works in Allegheny County for a while. Its combination of styles is unique in Pittsburgh, as far as old Pa Pitt knows. In form it is of the school Father Pitt likes to call American Fascist, the weighty classical style filtered through streamlined Art Deco that was popular for American public buildings between the World Wars, and of which the grandest example in Pittsburgh is the federal courthouse. But the details are Romanesque rather than classical—an acknowledgment of the lingering influence of the great Richardson’s greatest masterpiece, the Allegheny County Courthouse. The carved ornaments are Art Deco adaptations of medieval themes, except for the eagle above, which is not at all medieval, and which clasps the arms of Allegheny County in its talons.
The Fourth Avenue side. The County Office Building is roughly square, so the four sides are similar, except that this side lacks an entrance. But this was the side that was lit by the sun when Father Pitt was taking pictures. It took a lot of fiddling and adaptation to get the whole side of the building across a tiny narrow street, so you will see stitching errors and other anomalies if you enlarge the picture.
