Pittsburgh City-County Building, Government building in Downtown Pittsburgh, United States.
The Pittsburgh City-County Building is a ten-story government building in Neoclassical style located in downtown Pittsburgh, Pennsylvania. It connects Grant Street to Ross Street through a marble-lined lobby framed by bronze columns, and it houses both city and county offices.
The building was completed in 1917 to replace the former City Hall on Smithfield Street, which had become too small for Pittsburgh's growing administrative needs. Its construction followed the 1907 annexation of Allegheny City, which greatly expanded the responsibilities of local government.
The Supreme Court Room displays original furnishings designed by architect Henry Hornbostel alongside murals of historical lawmakers on the upper floors. These details show how the building's interior design conveys the authority and continuity of government.
The building sits on Grant Street in downtown Pittsburgh and is open during regular business hours for anyone needing administrative services or wanting to see the lobby. Because the building is large and spread across many floors, knowing which office you need before arriving will save time.
During construction in 1916, workers placed three separate time capsules inside three different cornerstones of the building, and their exact locations have never been found since. No search has uncovered them, so they remain sealed somewhere inside the walls to this day.
