Philadelphia City Hall is the seat of the municipal government of the City of Philadelphia in the U.S. state of Pennsylvania. Built in the ornate Second Empire style, City Hall houses the chambers of the Philadelphia City Council and the offices of the Mayor of Philadelphia.
This building is also a courthouse, serving as the seat of the First Judicial District of Pennsylvania. It houses the Civil Trial and Orphans' Court Divisions of the Court of Common Pleas of Philadelphia County. It also houses the Philadelphia facilities for the Supreme Court of Pennsylvania (which also holds session and accepts filings in Harrisburg and Pittsburgh).
Built using brick, white marble and limestone, Philadelphia City Hall is the world's largest free-standing masonry building and was the world's tallest habitable building upon its completion in 1894. It was designated as a National Historic Landmark in 1976; in 2006, it was also named a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.
