  • West of the Schuylkill River, the Cira Centre rises above a parking structure on the northwestern side of 30th Street Station. It is the tallest building in Philadelphia outside of Center City.
  • For a short period of time, this project was proposed to reach 475 feet with 31 floors.
  • A topping out ceremony took place on November 16, 2004.
  • Cira Centre was opened to tenants and the public in October 2005.
  • This is the first major high-rise office building in Philadelphia to be constructed outside of Center City.
  • The developers and tenants were successful in getting KOZ (Keystone Opportunity Zone) incentives for this structure which drastically reduces tax rates for several years.
  • Another faceted skyscraper design by the same architects, Torre de Cristal, was built 3 years later in Madrid.
  • The developers have also engaged the architects to design a shorter iteration of this building in Two Christina Centre for Wilmington, Delaware, about 40 miles to the southwest.
  • Because of the direct link to 30th Street Station, Cira Centre offers connections to all Amtrak Northeast Corridor Lines, SEPTA Regional Rail Lines, the Market-Frankford Subway, and trolley surface lines and buses.
  • The dynamic nighttime lighting scheme changes with different colors and patterns achieved via LEDs incorporated into the glass curtain wall.
