For unabashed excess, this building never ceases to amaze me. Each time I look at it I find a new feature. As a whole, it's close to overwhelming but in its details, each is a delight.
At 167 m (548 ft), including statue, it is the world's tallest masonry building: the weight of the building is borne by granite and brick walls up to 22 ft thick, rather than steel. The principal exterior materials are limestone, granite, and marble.
The building was designed by Scottish architect John McArthur, Jr., in the Second Empire style, and was constructed from 1871 until 1901 for a cost of $24 million. Originally designed to be the world's tallest building, by the time it was completed it had already been surpassed by the Washington Monument and the Eiffel Tower. With close to 700 rooms, City Hall remains the largest municipal building in North America and maybe the world.
The building is topped by an 11 m (37 ft), 27-ton bronze statue of city founder William Penn, one of
250 sculptures created by Alexander Milne Calder that adorn the building inside and out. The statue is the tallest atop any building in the world. Calder wished the statue to face south but it is a local legend that the citizens of the north side paid a bribe to have it face them.
For much of its history, City Hall remained the tallest building in Philadelphia, thanks to a "gentlemen's agreement." In 1987, it lost that distinction when One Liberty Place was completed. Penn's statue is hollow, and a narrow access tunnel through it leads to a small (22-inch-diameter) hatch atop the hat.
City Hall is a National Historic Landmark. In 2006, it was named an engineering landmark by the American Society of Civil Engineers.
I hope these few pics show-up, it's the first time I've tried this. But pics alone cannot do this showpiece justice.
And with holiday lighting:
