Philadelphia City Hall - world's largest free‑standing masonry building

Philadelphia City Hall is widely recognized as the world's largest free‑standing masonry building and is one of the largest municipal buildings in the United States. Completed in 1901, its load‑bearing brick and stone construction supports the 548‑foot tower topped by a 37‑foot bronze statue of William Penn. It was the tallest habitable building in the world when finished and remains notable for being constructed without a steel frame. City Hall houses municipal offices and dominates Center City Philadelphia.
