Contributor ChrisDantonio created this beautiful 360 degree aerial view of one of the great landmarks of Philadelphia, Pennsylvania: the statue of William Penn atop City Hall. City Hall was completed in 1901 in Center City, Philadelphia's central business district. The height of the building, including the statue, is 167 meters (just under 550 ft.). When completed, it was the tallest habitable building in the world. It remained the city's tallest building until a "gentlemen's agreement" on this point was lifted in the 1980's.
