Saint Clement's Church is a historic Anglo-Catholic parish in Logan Square, Center City, Philadelphia. It is part of the Episcopal Diocese of Pennsylvania. The church, designed by architect John Notman, was built in 1856. It originally incorporated a spire more than 200 feet (61 m) tall; this was found to be too heavy for the foundation and was removed in 1869. In 1929, the church building, which includes the parish house and rectory, and weighs 5000 tons, was lifted onto steel rollers and moved forty feet west to allow for the widening of 20th Street. On November 20, 1970, Saint Clement's Church was listed on the National Register of Historic Places.

The G. Fred DiBona Jr. Building, formerly known as the Blue Cross-Blue Shield Tower or IBX Tower, is a skyscraper in Philadelphia, Pennsylvania housing the headquarters of Independence Blue Cross (the Blue Cross-Blue Shield affiliated organization in the five-county Philadelphia area). The tower, built between 1988 and 1990, was designed by WZMH Architects, who also designed the CN Tower in Toronto, Ontario, Canada. It was renamed in 2005 after the company's president and CEO, who died of a brain tumor. Construction of the building consists of a steel skeleton surrounding a reinforced concrete core, similar to the construction of the new Comcast Center. The exterior is all blue glass except for granite accents at the base on the eastern and western facades and granite columns at the main entrance. It is currently the eighth-tallest building in Philadelphia. The building was originally intended to have a twin tower just to its west but the office-space requirements of the company ultimately ended plans for it. That lot remained vacant until an apartment building was built on it around 2015–2016. Alain Robert, the famous "French Spider-Man", scaled the building to the 44th floor in 1997, two years after the back-lit Blue Cross logo was added to the building's pediment.

The American Commerce Center was a proposed supertall skyscraper approved for construction in Philadelphia, Pennsylvania but cancelled due to the 2008 recession. The Comcast Innovation and Technology Center now stands on the site. At 1,510 feet (460 m) tall with 63 floors, the building would have dominated the Philadelphia skyline, standing almost 400 ft (120 m) taller than Philadelphia's tallest building, the Comcast Innovation and Technology Center. The office tower would have stood on the 19th Street side of Arch Street, and been connected to a 473 ft (144 m), 26-story hotel tower and public plaza along the 18th Street side of the block. The connection would have consisted of a multi-story skybridge with a garden on top.Of several supertall skyscrapers proposed for Philadelphia (including the Center City Tower and an early version of Comcast Center), this would have been the first to be constructed.The building would have been the tallest building in the United States by official height, or the second tallest by pinnacle height (including antennas) behind the Willis Tower at 1,729.8 feet (527 m) until the completion of 1,776-foot (541 m) One World Trade Center in New York City in 2014. On June 19, 2008, Philadelphia City Councilman Darrell Clarke introduced changes for the zoning legislation around 18th and Arch Streets which was the first step towards building the tower. On November 18, 2008, the City Planning Commission signed off on legislation needed for the zoning changes. According to the Philadelphia Daily News, "the developers will have to come back for approval of their building plan if Council passes the zoning bills." On December 11, 2008, the zoning changes in question were unanimously approved by City Council.On August 19, 2011, Liberty Property Trust acquired the development site from Hill International Real Estate Partners for a reported $40 million, which equates to $612 per square-foot ($2,008 per square-meter). The same company constructed the nearby Comcast Center and Liberty Place complex. However, the project was cancelled.

Commerce Square is a Class-A, high-rise office building complex in Center City Philadelphia, Pennsylvania, United States. Commerce Square consists of One and Two Commerce Square, two identical 41-story office towers 565 feet (172 m) high that surround a paved courtyard of 30,000 square feet (2,800 m2). Architecturally, the granite-clad towers feature setbacks on the north and south sides of the building and are topped with a pair of stone diamonds with cutout squares in the center. The towers were built as part an office-building boom Philadelphia was experiencing on West Market Street in the late 1980s. Designed by IM Pei & Partners (now called Pei Cobb Freed & Partners), the towers were developed in a joint venture between Maguire Thomas Partners and IBM. IBM also leased more than half of One Commerce Square for the company's Mid-Atlantic headquarters. Construction of the first phase, which included One Commerce Square, the plaza, and retail space, began in 1985 and was completed in 1987. The project's second phase, Two Commerce Square, did not begin until a lead tenant was secured for the building in 1990. Consolidated Rail Corporation (Conrail) agreed to be Two Commerce Square's lead tenant and make the skyscraper its corporate headquarters after a two-year search for office space in the region. Two Commerce Square ended the skyscraper construction boom of the 1980s when it was completed in 1992. No other office skyscraper was built in Philadelphia until Brandywine Realty Trust (NYSE: BDN) built the Cira Centre in 2005. In the 1990s, Commerce Square's lead tenants reduced their presence dramatically in the towers. IBM moved some of its operations out of Philadelphia in the early 1990s, and Conrail was bought by Norfolk Southern Railway and CSX Transportation later in the decade. Almost all of Conrail's operations were moved out of Philadelphia by the 2000s. Commerce Square was praised mainly for its design of two towers surrounding a plaza. Renowned Philadelphia urban planner Edmund N. Bacon praised Commerce Square and its plaza by saying it "will prove to be one of the finest commercial projects to be built in this century".
