Liberty Place is a skyscraper complex in Philadelphia. The complex is composed of a 61-story, 945-foot (288 m) skyscraper called One Liberty Place, a 58-story, 848-foot (258 m) skyscraper called Two Liberty Place, a two-story shopping mall called the Shops at Liberty Place, and the 14-story Westin Philadelphia Hotel. Prior to the construction of Liberty Place, there was a gentlemen's agreement not to build any structure in Center City higher than the statue of William Penn on top of Philadelphia City Hall. The tradition lasted until 1984 when developer Willard G. Rouse III of Rouse & Associates announced plans to build an office building complex that included two towers taller than City Hall. There was a great amount of opposition to the construction of the towers with critics believing breaking the height limit would lead to construction of many more tall skyscrapers, ruining the livability and charm of Center City. Despite the opposition, construction of One Liberty Place was approved and the first phase of the project began in 1985 and was completed in 1987. One Liberty Place became the city's first skyscraper. The iconic design and spire make the complex a recognizable part of the Philadelphia skyline.
Phase 2 of the project included Two Liberty Place, a hotel, a shopping mall, and a parking garage. Construction began 1988, after Cigna agreed to lease the entirety of the skyscraper for use as that company's world headquarters. Construction was completed in 1990, making Two Liberty Place the second-tallest building in the city. The two towers held their place as first- and second-tallest buildings in Philadelphia until the Comcast Center was topped off in 2007, which was surpassed in 2017 by the Comcast Technology Center. Liberty Place was received enthusiastically by critics and led to the construction of other tall skyscrapers giving Philadelphia what architecture critic Paul Goldberger called "one of the most appealing skylines of any major American city".Liberty Place was designed by architect Helmut Jahn and his firm Murphy/Jahn. The steel and blue glass skyscrapers were heavily influenced by New York City's Chrysler Building. The major influence is the spire made of gabled angular setbacks. Two Liberty Place's spire is shorter and squatter, a design influenced by the needs of tenant Cigna. In the 2000s, Cigna reduced its presence in the tower, which led to the owners converting the upper floors into 122 luxury condominiums. Below the two towers is the 289 room Westin hotel and the 143,000 square feet (13,000 m2) Shops at Liberty Place. The main feature of the mall is a round atrium topped by a large glass dome.
