Observing The Construction Of Mellon Bank Center and Two Liberty Place
In 1984, plans were approved for the first office tower to rise above the unwritten Gentleman’s Agreement height above the statue of William Penn. One Liberty Place broke ground in 1985 and was under construction until the end of 1987, starting a new construction boom for the city that revitalized the city’s skyline. One Commerce Square had topped out the summer before One Liberty Place rose, but, shortly after the completion of One Liberty Place, the structure of the Independence Blue Cross Tower joined the skyline. By the end of 1988, the Bell Atlantic Tower was also rising, eventually bulking up the skyline by 1989.
