With 14 ½ acres of floor space, this is the largest municipal building in the United States. Built on one of five squares designated by founding father William Penn as Center Square, its Old City site once marked the geographic center of Philadelphia. 

Begun in 1871, this imposing Second Empire masterpiece, with its 22-foot-thick exterior walls, granite floors, marble columns and 548-foot masonry clock tower, took 30 years to complete. Hired by architect John MacArthur, Jr., Scottish-born sculptor Alexander Milne Calder spent 20 years creating 250 bronze and marble sculptures for City Hall, the greatest achievement of his career.

Guided tours of this National Historic Landmark are given Monday-Friday at 12:30 p.m., starting from Room 121. The tower observation deck is open Monday-Friday, 9:30 a.m. – 4:15 p.m.
