Philadelphia is the largest city in Pennsylvania State. The city went through a construction boom in the 1970's and 1980's that saw the rise of more than 20 high rise buildings. The city’s history of constructing tall buildings dates back to 1754 when a steeple was added to the Christ Church. In the 20th century, a gentleman’s agreement prevented building from rising above the tallest building, the Philadelphia City Hall which was 548 feet tall. The city has twice held the record for the tallest building in North America, first was the Christ Church and later the City Hall. In 1987, due to urbanization and the need for leasable space, the agreement was broken by the construction of the One Liberty Place. The Comcast Center is Philadelphia's tallest building and the 19th tallest in the US. In 2014, the construction of the Comcast Innovation and Technology Center began, it is expected to surpass the Comcast Center by 146 feet to be the tallest building in Philadelphia and 8th in the US.
