Design Matters

Henry Hornbostel designed this Beaux Arts public building with elements of the City Beautiful Movement (built 1915-1917). He also designed most of the furniture, much of which is still in use today. A prolific architect with more than 225 buildings to his name, Hornbostel was also the architect of Soldiers and Sailors Memorial Hall and the Carnegie Institute of Technology (now CMU).

Your Experience:  

After exploring the Lobby of the Pittsburgh City-County Building, visitors will have the unique opportunity to visit the Mayor's personal office. In addition, visitors can explore the Hall of Mayors, Council Chamber, and the rarely opened Pittsburgh Vault, containing the the city’s archives.

Building Description:

The City of Pittsburgh is proud to open the doors of the historic City-County Building to the public, allowing a unique behind the scenes look at the seat of Pittsburgh's government – including the Mayor’s Office and City Council.

Built from 1915-17, the City-County Building was designed by renowned architects Henry Hornbostel & Edward Lee as the 3rd seat of government for the City Of Pittsburgh. A gift to itself for Pittsburgh’s Incorporation Centennial in 1916, the City-County Building was constructed from 1915-17.

This magnificent space was considered to be temporary! Now, 100 years later we happily open the doors to what we foresee as our permanent home, to the public.

Be sure to visit the City Council Chambers and City vault while you are here!
