The Allegheny County Courthouse is it Pittsburgh Pennsylvania also includes the jail, and together are two of the oldest buildings in Pittsburgh (GoogleUser). These buildings are also characteristically Richardsonia Romanesque. The are made almost completely of stone and use circular arches. However, they are less medieval looking and are decently proportioned. This building is massive and has a large tower extending high above the height of the rest of the building, which originally made the courthouse the tallest structure in Pittsburgh (GoogleUser). This building is not as dark as some of the other Hobson Richardson designs.

The bridge in the bottom photo connects the bridge and the courthouse and was modeled after of a similar Venetian structure (GoogleUser).
