Per Wikipedia:
The Ritz-Carlton Philadelphia is a 394 feet (120-meter) 30-story skyscraper located south of City Hall in the Center City of Philadelphia, Pennsylvania. It was built in 1930-1931 as the Girard Trust Building. The tower was actually an addition to a domed low-rise building which was constructed in 1908. It was then renamed Two Mellon Plaza. One Meridian Plaza (1972-1999) was connected to this building. Shortly after One Meridian Plaza’s demolition, the building was converted in 2000 into a 330-room Ritz-Carlton hotel. Responsible for the building’s conversion are James Garrison and Dr. George C. Skarmeas.
On the former site of One Meridian Plaza stands The Residences at the Ritz Carlton of Philadelphia, constructed in 2009.
The architect of the Girard Trust Building was McKim, Mead & White. The building is located on the site formerly occupied by the West End Trust Building (1898-1928).
